Medicare is the largest public health insurance service provided by the U.S. Federal government.
All American citizens and some permanent residents that meet certain requirements are eligible for Medicare Part A when they reach at the age of 65. They must sign up for and pay a monthly premium for Part B.
The main differences between rich and poor countries with respect to causes of death:
In high-income countries more than two thirds of all people live beyond the age of 70 and predominantly die of chronic diseases: cardiovascular disease, chronic obstructive lung disease, cancers, diabetes or dementia. Lung infection remains the only leading infectious cause of death.
In middle-income countries, nearly half of all people live to the age of 70 and chronic diseases are the major killers, just as they are in high-income countries. Unlike in high-income countries, however, tuberculosis, HIV/AIDS and road traffic accidents also are leading causes of death.
In low-income countries less than one in five of all people reach the age of 70, and more than a third of all deaths are among children under 15. People predominantly die of infectious diseases: lung infections, diarrhoeal diseases, HIV/AIDS, tuberculosis, and malaria. Complications of
pregnancy and childbirth together continue to be leading causes of death, claiming the lives of both infants and mothers.
Cancer is a condition where cells in a specific part of the body grow and reproduce uncontrollably. The cancerous cells can invade and destroy surrounding healthy tissue, including organs. Untreated, these cells can potentially
spread to other tissues in the body, including organs, which is known as secondary or metastatic cancer.
There are more than 200 different types of cancer, the most common ones are breast, lung, prostate and bowel. Each cancer is diagnosed and treated in a particular way. One in two people develop some kind of cancer during their lifetime,
most cases of cancer are in people aged 50 and over. Changes to the body's normal processes or unusual, unexplained symptoms can sometimes be an early sign of cancer, such as a lump that suddenly appears on the body, unexplained bleeding,
and changes to your bowel habits.
Nearly 2 million Americans have been diagnosed with cancer in 2023, and around 610,000 people have died of the disease; anyone can develop cancer, but 88% of those in the U.S. diagnosed with cancer are 50 or older,
and 57% are 65 or older, the American Cancer Society said.
Cancer was the second leading cause of death, after heart disease, in the United States. In 2020, there were 602,350 cancer deaths; 284,619 were among females and 317,731 among males.
136,084 people died of lung cancer (63,135 females and 72,949 males).
51,869 people died of colorectal cancer (23,826 females and 28,043 males).
46,774 people died of pancreatic cancer (22,495 females and 24,279 males).
42,275 females died of breast cancer.
32,707 males died of prostate cancer.
28,227 people died of liver and intrahepatic bile duct cancer (9,591 females and 18,636 males).
For the cancer treatment using chemotherapy, late effects may include dental problems, early menopause, eye problems, hair loss, hearing loss, heart problems, increased risk of other cancers, infertility, loss of taste, lung disease, nerve damage, osteoporosis (bone loss), and reduced lung capacity.
For the cancer treatment using hormone therapy, late effects may include blood clots, hormonal change, hot flashes, increased risk of other cancers, menopausal symptoms, osteoporosis, and sexual side effects.
For the cancer treatment using radiation therapy, late effects may include cavities and tooth decay, dry mouth, early menopause, hair loss, heart and vascular problems, hypothyroidism, increased risk of other cancers, increased risk of stroke, infertility, intestinal problems,
lung disease, lymphedema, memory problems, and osteoporosis.
Late side effects from surgery depend on the type of cancer and the surgery location in the body; lymphedema is most commonly caused by the removal of or damage to a lymph node as a part of this cancer treatment.
Late effects are unknown for the cancer treatment with targeted therapy or immunotherapy.
Cancer, an incurable disease, is a deadly terminal disease known worldwide. There are over 200 different types of cancers.
While 1 in every 3 women in her lifetime, is likely to die because of breast cancer,
colo-rectal cancer, ovarian cancer, pancreatic cancer, and lung and bronchial cancer, 1 in every 2 men in his life time, mostly dies because of lung & bronchus cancer, prostate cancer, colon & rectum cancer, pancreas cancer, and liver & intrahepatic bile duct cancer.
In the US, cancer usually develops in older people; 86% of all cancers are diagnosed in people 50 years of age or older. Lifetime risk refers to the probability that an individual will develop or die from cancer over the course of a lifetime.
The lifetime risk of developing cancer is 42% in men and 38% in women.
Prostate cancer is cancer that occurs in the prostate, which is a small walnut-shaped gland in males that produces the seminal fluid that nourishes and transports sperm.
Prostate cancer is diagnosed with a biopsy. The most common reason for a man to undergo a prostate biopsy is due to an elevated prostate-specific antigen level (PSA), determined by a blood test. It's not clear what causes prostate cancer. Prostate cancer may cause no signs or symptoms in its early stages;
when it's more advanced, signs and symptoms may include trouble urinating, decreased force in the stream of urine blood in the urine and the semen, and/or erectile dysfunction.
Prostate cancer, which is the most commonly diagnosed type of cancer, is the second leading cause of cancer in men. One in 8 men has been diagnosed with prostate cancer at some point in their lives.
Prostate cancer incidence increases with age, the older men are, the greater their chance of developing this disease. Around 60% of all prostate cancers are diagnosed in men over the age of 65
(1 in 55 for ages 50 to 59, 1 in 20 for ages 60 to 69, and 1 in 12 for ages 70 and older).
Many cancers are found too late and most of them show no symptoms until later stages, and treatment options may be limited and the outcomes are often deadly. Cancer blood tests and other laboratory tests may help doctors make a cancer diagnosis.
Common blood tests used to diagnose cancer include
Complete Blood Count (CBC) (used to detect if too many or too few of a type of blood cell or abnormal cells are found in blood);
Blood Protein Testing (used to detect certain abnormal immune system proteins (immunoglobulins) that are sometimes elevated in people with multiple myeloma;
Tumor Marker Tests (used to detect chemicals made by tumor cells in blood);
and
Circulating Tumor Cell Tests (used to detect cells that have broken away from an original cancer site and are floating in the bloodstream).
Cancer that begins in the colon is called colon cancer, and cancer that begins in the rectum is called
rectal cancer. Cancer that starts in either of these organs may also be called colorectal cancer.
Each year around 143,000 people in the U.S. are diagnosed with colorectal cancer. It is the fourth most common cancer in men, after
skin,
prostate, and
lung cancer.
The colon and rectum make up the large intestine (or large bowel), which is part of the digestive system, also called the gastrointestinal (GI) system. Colon cancer, which is a type of cancer that begins in the large intestine (colon), is sometimes called
colorectal cancer (CRC), a term that combines colon cancer and rectal cancer, which begins in the rectum. CRC, which typically affects 33% of older adults (male or female),
usually begins as small, noncancerous (benign) clumps of cells called polyps that form on the inside of the colon. Over time some of these polyps can become CRC. Finding and removing polyps can prevent CRC. When abnormal tissue or cancer is found early, it may be easier to treat.
By the time symptoms appear, cancer may have begun to spread. CRC is the second leading cause of cancer deaths in the US; 1 out of 20 people will develop CRC in their lifetime. CRC often has no obvious signs or symptoms;
when symptoms appear, they'll likely vary, depending on the cancer's size and location in the large intestine. If CRC develops, many treatments are available to help control it, including surgery, radiation therapy and drug treatments, such as chemotherapy, targeted therapy and immunotherapy.
When detected early people with CRC have a greater than 90% 5-year survival rate.
Colorectal cancer is the No. 2 killer in the US, reports the CDC, claiming more than 50,000 lives in 2013.
A multi-cancer early detection test, Galleri, developed by Grail, Inc., an American healthcare company, can detect over 50 types of cancers — over 45 of which lack recommended
screening today — with a low false positive rate, through a single blood draw. The Galleri test looks for signals present in the blood that may be associated with cancer at the time of the blood draw. If a cancer signal is detected, Galleri results can point to where in the body the cancer is coming from. However, the Galleri
test does not diagnose cancer and not all cancers may be detected in the blood. A bone marrow biopsy, which involves removing a small sample of the bone marrow inside bones for testing, may also help confirm a diagnosis of a blood cancer.
Increased risk for getting liver cancer when a person has symptoms that may include discomfort in the upper abdomen on the right side, a swollen abdomen, a hard lump on the right side just below the rib cage, pain near the right shoulder blade or in the back,
yellowing of the skin and whites of the eyes (jaundice), easy bruising or bleeding, unusual tiredness, nausea and vomiting, loss of appetite, and/or weight loss for no known reason.
Multiple sclerosis (MS) is a long-lasting (chronic) disease of the central nervous system that attacks the myelin, the protective covering surrounding nerves,
resulting in a variety of symptoms, including weakness, loss of balance, pain, tingling and fatigue; MS is an unpredictable disease that affects people differently. Some people with MS may have only mild symptoms; nearly a million Americans
have MS; the condition is three times more common among women than men and often begins between ages 20 and 50, during the prime of life.
After an eye exam, the doctor must give you a copy of your prescription for free and with no strings attached; for glasses, the patient must receive a copy of their prescription after the exam; for contacts, the doctor must provide
it after the fitting is complete - whether the patient asks for it or not, it’s the law, required by The Federal Trade Commission’s Contact Lens Rule and the Eyeglasses Rule.
Suicide was responsible for 48,183 deaths in 2021, which is about one death every 11 minutes. Doctors are dying by suicide at higher rates than the general population.
Around 400 physicians ended their own life a year in the US, the equivalent of one medical school graduating class annually.
Surgeons, who often suffer high rates of burnout, ergonomic injuries,
miscarriages and infertility and are expected to take responsibility for what happens to their patients, have some of the highest known rates of suicide;
of 697 physician suicides reported to the CDC between 2003 and 2017, at least 71 were surgeons.
Amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's Disease, is a rare neurological, progressive and incurable disease that affects motor neurons.
It is caused by the death of nerve cells in the brain and spinal cord that control the movement of muscles. Early symptoms include muscle twitches in the arm, leg, shoulder, or tongue, muscle cramps, tight and stiff muscles (spasticity), muscle weakness
affecting an arm, a leg, the neck, or diaphragm, slurred and nasal speech, and difficulty chewing or swallowing.
The Amyotrophic lateral sclerosis (ALS) disease often begins with muscle twitching and weakness in an arm or leg, trouble swallowing or slurred speech, but as it progresses it profoundly impacts on the ability to move, talk and even breathe. The exact cause of the disease is still not known.
A small number of cases are inherited. Most people with ALS die from respiratory failure, usually within three to five years from when the symptoms first appear. However, about 10 percent of people with ALS survive for a decade or more.
Falls usually happen because gradual changes to bodies make walking difficult as part of the normal ageing process (e.g., poorer eyesight, muscle weakness), or caused by an illness or condition (e.g.,
low blood pressure, diabetes, Alzheimer’s disease,
Parkinson’s disease); falls can cause fragility fractures, which are most common in bones of the spine, wrists and hips, and other injuries that require lengthy hospital care and long-term effects;
if you have fallen more than once in the past 6 months, you are more likely to fall again.
When the heat beats, blood is drawn into its two upper chambers, stayed there briefly and then pumped out forcefully through its two lower chambers. An arrhythmia, or irregular heartbeat
(a problem with the rate or rhythm of heartbeat) occurs when the heart beats too quickly, too slowly, or with an irregular rhythm, and it can lose coordination among its chambers; this breakdown can lead to fatigue, shortness of breath,
a heart attack or stroke. People who have Type 2 diabetes are 34% more likely to develop
an arrhythmia (or Afib) than people without diabetes.
The heart beats about 100,000 times per day (roughly 3 billion times during the course of an average lifetime); an adult heart beats about 60 to 80 times per minute (between 60 and 100 beats per minute is normal).
The heart pumps about 5.7 liters of freshly oxygenated blood every minute (it can rise to more than 35 liters per minute when exercising), leaves the heart and enters the bloodstream throughout the body.
As of 6/2023 there were around 529 million people in the world living with diabetes, and more than 4.44 million deaths every year; 8 deaths every minute.
It's projected that this will more than 1.3 billion people with diabetes by 2050. The top 10 countries, in numbers of sufferers, are India, China, USA, Indonesia, Japan, Pakistan, Russia, Brazil, Italy and Bangladesh.
Diabetes affects over 30 million American adults and children and 1 in 4 of them don’t know they have it; more than 84 million American adults have
prediabetes, and 90% of them don’t know they have it.
Around 30.3 million Americans have had diabetes, of which around 12.0 million people age 65 and older and about 193,000 Americans under age 20. Around 1.5 million Americans are
diagnosed with diabetes every year. The rates of diagnosed diabetes in adults by race/ethnic background are
7.4% of non-Hispanic whites,
8.0% of Asian Americans (of which 4.3% for Chinese, 8.9% for Filipinos, 11.2% for Asian Indians, and 8.5% for other Asian Americans),
12.1% of Hispanics (of which 8.5% for Central and South Americans, 9.0% for Cubans,
13.8% for Mexican Americans, and 12.0% for Puerto Ricans),
12.7% of non-Hispanic blacks, and 15.1% of American Indians/Alaskan Natives.
37.3 million people have diabetes—that’s 11.3% of the US population.
28.7 million people have been diagnosed with diabetes.
8.5 million people who have diabetes have not been diagnosed and do not know they have it.
96 million US adults have prediabetes.
26.4 million adults 65 or older have prediabetes.
In 2019, 37.3 million Americans, or 11.3% of the population, had diabetes. Nearly 1.9 million Americans have type 1 diabetes, including about 244,000 children and adolescents Diagnosed and undiagnosed:
Of the 37.3 million adults with diabetes, 28.7 million were diagnosed, and 8.5 million were undiagnosed.
Diagnosed: 28.7 million people of all ages had been diagnosed with diabetes (8.7% of the population).
28.5 million were adults ages 18 years or older.
283,000 were children and adolescents younger than age 20, including 244,000 with type 1 diabetes.
Undiagnosed: 8.5 million adults ages 18 years or older had diabetes but were undiagnosed (23% of adults with diabetes were undiagnosed).
Among U.S. adults ages 18 years or older, 96 million—more than 1 in 3—had prediabetes in 2019.
People with the type 1 form of diabetes have an autoimmune disorder and are unable to produce sufficient amounts of the hormone insulin,
which is made by the pancreas; type 1 diabetes accounts for about 5% of all diabetes cases.
The vast majority of Americans with diabetes have type 2 form of the disorder, in which the body does not manage its insulin levels correctly; type 2 diabetes accounts for about 90% to 95% of all diagnosed cases of diabetes.
People are at risk for developing prediabetes or type 2 diabetes if they are overweight and age 45 or older, and physically active less than 3 times a week, or if they have a parent, brother, or sister with type 2 diabetes.
Diabetes is a disease in which your blood glucose, or blood sugar, levels are too high.
Most of the food you eat is broken down into sugar (also called glucose) and released into your bloodstream. When your blood sugar goes up, it signals your pancreas to release insulin.
Insulin is a hormone that helps the glucose (blood sugar) get into your body’s cells for use as energy
With type 1 diabetes, your body does not make insulin.
With type 2 diabetes, the more common type, your body does not make or use insulin well. Without enough insulin, the glucose stays in your blood.
Diabetes can cause serious health problems, such as heart disease, vision loss, and
kidney disease.
Diabetes is a long-term condition that causes high blood sugar levels; approximately 10% of all diabetes cases are type 1, for which the body does not produce insulin; the rest 90% are type 2, for which the body does not produce enough insulin for proper function.
The most common diabetes symptoms include frequent urination, intense thirst and hunger, weight gain, unusual weight loss, fatigue, cuts and bruises that do not heal,
male sexual dysfunction, numbness and tingling in hands and feet.
In the U.S. about 40 children a year die from heatstroke, either because they were left or became trapped in a car. That's about one child every 10 days killed in a hot car. There were over 940 child hot car deaths since 1998.
In the U.S. around 80% of the population have received at least one dose, 68% got fully vaccinated, and 34% received a booster dose; however, as of 2/2023 the COVID pandemic is still
killing more than 450 people per day — four times as many as die in auto accidents.
LDL, known as "bad" cholesterol, should be under 130 for most people; 100 for people at high-risk; under 70 for those at the highest risk, such as those who have just survived a heart attack.
Cholesterol is assembled in the liver and released into the bloodstream, cholesterol and triglycerides form the core of all lipoproteins, triglyceride levels should be kept low; high density lipoproteins (HDL) are called good cholesterol, it removes cholesterol from the artery walls and the bloodstream; Low density lipoproteins (LDL) are considered bad cholesterol, it deposits cholesterol in the artery walls and begins
the process of atherosclerosis; 20% Triglycerides + HDL + LDL = Total Cholesterol.
One of major factors caused the cardiovascular disease is higher levels of cholesterol and triglycerides. Cholesterol and triglycerides are necessary for our life. While cholesterol is essential for body to work properly, triglycerides provide the fuel needed for body cells to function. Total cholesterol (TC) is an estimated measure bad cholesterol (LDL), good cholesterol (HDL) and triglycerides.
TC = LDL + HDL + (Triglycerides/5). Goal: less than 200 mg/DL for TC.
LDL, or bad cholesterol, carried cholesterol to tissues in your body. Higher levels of LDL in your blood mean that cholesterol is being stick to your artery walls.
The arteries may develop a fatty buildup called atherosclerosis. Goal: less than 100 mg/dL
for LDL. HDL, or good cholesterol, carried cholesterol away tissues in your body. Higher levels of HDL in your blood mean that cholesterol is being
carried away from artery walls to the liver and then eliminated from the body. Goal:
greater than 60 mg/dL for HDL. Triglycerides are another fatty substance in the blood. Higher levels of
triglycerides in your blood mean larger thickening of the artery walls, which causes higher risk of stroke, heart attack and heart disease.
Goal: less than 150 mg/dL for Triglycerides. Some commonly prescribed medications lowering your cholesterol are:
Crestor,
Lescol,
Lipitor,
Pravachol and
Zocor.
The first heart transplant and subsequent ongoing research in cardiac transplantation at the University of Cape Town's Groote Schuur Hospital, where
Christiaan Barnard with his team performed the world’s first human-to-human heart transplant operation on 3 December 1967. The first heart transplant patient survived only 18 days, four of first 10 patients survived for more than one year, two living for 13 and 23 years.
Forty-nine consecutive heterotopic heart transplants were performed in Cape Town between 1974 and 1983, with moderately good results for that era; three of the first five patients of this 49-patient group survived more than 10 years.
Dr. Robert Jarvik implants a permanent artificial heart, the Jarvik 7, into retired dentist Barney Clark at the University of Utah on December 2, 1982. The heart, powered by an external compressor, keeps Dr. Clark alive for 112 days.
The next several implantations of the Jarvik-7 heart were conducted by Humana, a large health care insurance company. The second patient, William J. Schroeder, survived 620 days.
Dr. Norman Edward Shumway (February 9, 1923 – February 10, 2006) was a pioneer of heart surgery at Stanford University. Norman Shumway is widely regarded as the father of heart transplantation;
he successfully transplants a heart into 54-year-old steelworker Mike Kasperak, who survives for 14 days in 1968.
Stroke is the number three killer in the US, affecting almost 800,000 people each year.
Top risks for a stroke include high-fat diet, being single, being unhappy, being obese, smoking, and being born in the wrong demographic.
There are three types of muscles in the human body: cardiac, smooth and skeletal.
Cardiac muscle makes up the wall of the heart. Smooth muscles make up the walls of the intestine, the uterus, blood vessels, and internal muscles of the eye. Skeletal muscles are attached to the bones; contraction of the skeletal muscles helps limbs and other body parts move.
The hardest working muscle is the heart. It pumps out 2 ounces (71 grams) of blood at every heartbeat. Daily the heart pumps at least 2,500 gallons (9,450
liters) of blood. The heart has the ability to beat over 3 billion times in a person’s life.
About 500,000 heart stent procedures are performed each year in the United States, and the researchers estimate that about a fifth of those are for people with stable heart disease.
Of those, about a quarter — or an estimated 23,000 procedures — are for people without any chest pain.
A stent is placed in a weak artery to improve blood flow and help prevent the artery from bursting, but it is not better at preventing a heart attack or prolonging survival than lifestyle changes,
such as exercising and taking statins to lower cholesterol.
More than 400 million people have cardiovascular illness worldwide; about 18 million people around the world died from heart disease in 2015. Those diseases were highest in countries across sub-Saharan Africa, Central Asia, and eastern and central Europe. Central and eastern Europe also had high heart disease-driven death rates,
alongside Iraq, Afghanistan and several island nations in the South Pacific. The lowest heart disease incidence was found in Singapore, Japan, South Korea, Chile and Argentina. Risk factors for heart disease, like high blood pressure, poor diet, high cholesterol, tobacco smoking, excessive alcohol use and obesity, are common throughout most of the world.
Cardiovascular diseases (CDVs) are the number one cause of death worldwide and accounts for 30% of all deaths, more people die annually from CVDs than from any other cause.
An estimated 17.9 million people died from CVDs in 2016, representing 31% of all global deaths. Of these deaths, 85% are due to heart attack and stroke.
Over three quarters of CVD deaths take place in low- and middle-income countries. South Asians (from Bangladesh, Bhutan, India, the Maldives, Nepal, Pakistan, and Sri Lanka) with around 2 billion
people comprise 60% of the world’s heart disease cases, even though they make up only a quarter of the planet’s population. Asian descent, a growing population of about 5.4 million, have disproportionately higher risk of stroke, heart attacks and other cardiovascular ailments that are not
explained by widely known risk factors, such as high blood pressure, diabetes or smoking.
Most cardiovascular diseases can be prevented by addressing behavioral risk factors such as tobacco use, unhealthy diet and obesity, physical inactivity and harmful use of alcohol using population-wide strategies.
A family history of early heart disease is a risk factor for coronary heart disease. Over time, unhealthy lifestyle habits increase higher risk of coronary heart disease because they can lead to plaque buildup in the heart’s blood vessels. These include being physically inactive,
not getting enough good quality sleep, smoking tobacco or long-term exposure to secondhand smoke, stress, and unhealthy eating patterns.
Coronary heart disease is a type of heart disease that develops when the arteries of the heart cannot deliver enough oxygen-rich blood to the heart.
Coronary heart disease is often caused by the buildup of plaque, a waxy substance, inside the lining of larger coronary arteries. This buildup can partially or totally block blood flow in the large arteries of the
heart. The risk of coronary heart disease goes up with the number of risk factors and how serious they are. Some risk factors such as high blood pressure
and high blood cholesterol can be changed through heart-healthy lifestyle changes.
Other risk factors, such as sex, older age, family history and genetics, and race and ethnicity, cannot be changed. The risk for coronary heart disease starts to increase around age 45 for men and 55 for women. People who deal with toxins, radiation, or other hazards, have a lot of stress at work,
sit for long periods, work more than 55 hours a week, work long, irregular, or night shifts that affect their sleep, have at higher risk of coronary heart disease.
Cardiovascular diseases are the leading cause of death globally; most cardiovascular disease affects older adults. Cardiovascular diseases caused 17.9 million deaths (32.1%) worldwide in 2015,
up from 12.3 million (25.8%) in 1990. In the United States 11% of people between 20 and 40 have cardiovascular disease, while 37% between 40 and 60, 71% of people between 60 and 80, and 85% of people over 80 have cardiovascular disease. The average age of death from coronary artery disease in the developed world is around 80 while it is around 68 in the developing world.
Cardiovascular disease onset is typically seven to ten years earlier in men as compared to women; cardiovascular disease symptoms may be different for men and women; men are more likely to have
chest pain; women are more likely to have other symptoms along with chest discomfort, such as shortness of breath, nausea and extreme fatigue.
Older people who take a low-dose aspirin (100 mg or less) daily may be 20 percent more likely to develop anemia than those who do not. Anemia develops when a person's blood produces a lower-than-normal amount of healthy red blood cells, which are needed to carry oxygen to tissues throughout the body.
Anemia causes the lack of oxygen can make people feel tired or weak, shortness of breath, dizziness, headaches, or an irregular heartbeat. People often took low-dose aspirin, which can thin the blood and help prevent clots, in hopes of preventing a heart attack or stroke. However, taking low-dose aspirin is not effective for most people who have not already had a cardiovascular issue.
Heart attacks are about three times more likely to occur in the morning, when blood pressure and platelet activity are typically at their highest levels. Taking a daily aspirin helps thin the blood and prevent platelets from clumping, lowering the likelihood of heart attacks and stroke.
However, aspirin users were about 30 percent more likely to have a serious gastrointestinal bleeding event, a side effect of frequent aspirin use.
A highly anticipated trial results show that invasive procedures, stents and bypass
surgery are no more effective than drugs for stable heart disease, these should be used more sparingly in patients with stable heart disease and the decision to use them should be less rushed. The ability to implant
stents using a catheter inserted through blood vessels in the arm or groin have been clearly demonstrated to save lives in people who are suffering from a heart attack;
however, as heart medicines such as statins have improved, there has been active debate about whether stents and other invasive procedures are
more effective for people who aren’t in the throes of a heart attack but have stable heart disease.
Cardiovascular disease (CDV) killed 864,480 American in 2005; 151,000 of CDV deaths were under age 65. 16.8 million Americans
had a heath attack or angina; 6.5 million Americans had a stroke; 5.7 million live with heart failure; 309,000 Americans died from sudden heart attack.
About 6 million people each year go to hospitals with chest pain; however, only a small fraction are truly having a heart attack. CT scans are increasingly used to diagnose heart attack, but they put out a lot of radiation, which may raise a person's chances of developing cancer.
About 10,000 blood centers in 168 countries report collecting a total of 108 million blood donations globally, of which around 50% is collected in the high-income countries, home to 18% of the world’s population.
The liver (located in the upper abdomen near the stomach, intestines, gallbladder, and pancreas), is essential for digesting food and ridding the body of toxic substances. It performs storing nutrients, removing waste products and worn-out cells from the blood, filtering and processing chemicals in food, alcohol, and medications, and producing bile that helps digest fats and eliminates waste products.
A liver hemangioma is a noncancerous (benign) mass in the liver made up of a tangle of blood vessels; these lumps,
which consist of blood vessels and are usually harmless, are common and are estimated to occur in up to 20% of the population. An estimated 5% of American adults have small liver hemangiomas that cause no symptoms and do not need treatment;
larger hemangiomas can cause pain or discomfort.
The signs of liver disease (may not be liver cancer) may include abdominal pain and swelling, skin and eyes that appear
yellowish (jaundice), swelling in the legs and ankles, itchy skin, dark urine color, pale stool color, chronic fatigue, nausea or vomiting, loss of appetite, and/or tendency to bruise easily.
Most cases of liver cancer, hepatocellular carcinoma (HCC), occur in people who already have signs and symptoms of chronic liver disease, such as cirrhosis caused by hepatitis B or
hepatitis C infection. The risk of HCC for people with type 2 diabetes
is greater (from 2.5 to 7.1 times the non-diabetic risk) depending on the duration of diabetes and treatment protocol. HCC often doesn’t show symptoms until the advanced stages of the disease, but some people may experience abdominal pain or tenderness, easy bruising or bleeding, enlarged abdomen, unexplained weight loss,
and jaundice. HCC remains associated with a high mortality rate, in part related to initial diagnosis commonly at an advanced stage of disease.
Globally, each year over 750,000 people are diagnosed with liver cancer, hepatocellular carcinoma (HCC), most often in late stages of the disease. Almost 50% of all cases are diagnosed in China in large part due to the prevalence of hepatitis B and C, fatty foods and obesity, alcohol, and aflatoxin (a carcinogenic mould found in contaminated food, especially rice).
There are limited treatments available for people across all stages of liver cancer, and even less if diagnosed at the advanced stage. Despite the high prevalence of HCC, people with the disease still have few options and a low survival rate. In fact, less than 50% of people diagnosed with advanced HCC will survive more
than a year after diagnosis. Treatments currently available across different stages of the disease include surgery to remove masses, radiation, liver transplant, transarterial chemoembolisation, chemotherapy,
freezing or heating the cancer cells, and tyrosine kinase inhibitors.
Cancer is a group of diseases involving abnormal cell growth with the potential to invade or spread to other parts of the body.
Many cancers can be prevented by not smoking, maintaining a healthy weight, not drinking too much alcohol, eating plenty of vegetables, fruits and whole grains, vaccination against certain infectious diseases, not eating too much processed and red meat, and avoiding too much sunlight exposure.
Tobacco use is the cause of about 22% of cancer deaths, Another 10% is due to obesity, poor diet, lack of physical activity and drinking alcohol.
Other factors include certain infections, exposure to ionizing radiation and environmental pollutants.
In the U.S., each year there are about 56,000 new cases of thyroid cancer, and the majority of those diagnoses are papillary thyroid cancer — the most common type of thyroid cancer. Some thyroid cancer signs and symptoms include a hoarse voice, neck pain, and enlarged lymph nodes. Although as much as 75% of the population will have thyroid nodules, the vast majority are benign. Thyroid cancer can occur in any age group and its aggressiveness increases significantly in older patients.
Females are more likely to have thyroid cancer at a ratio of 3:1. Fewer than 1% of all thyroid nodules are malignant (cancerous). A nodule that is cold on scan is more likely to be malignant. However, the majority of these are benign as well.
Thyroid cancer does not always cause symptoms; often, the first sign of thyroid cancer is a thyroid nodule. Most thyroid cancers are very curable. In fact, the most common types of thyroid cancer (papillary and follicular thyroid cancer) are the most curable.
In younger patients, both papillary and follicular cancers have a more than 97% cure rate if treated appropriately.
Cancer has a major impact on society in the U.S. and across the world. People who have cancer may have questions about how serious their cancer is and the chances of survival. The answer depends on
the type of cancer, the stage of the cancer, cancer's grade, age, how healthy they are, and how they respond to treatment. The period of time may be 1 year, 2 years, 5 years, etc. In the U.S. the average number of new cases
of cancer is 440 per 100,000 men and woman per year, and the average number of cancer deaths is 163.5 per 100,000 people. In 2018, there were around 1,735,350 new cases of cancer, and 609,640 people died from the disease.
In 2017, there were 15,270 children and adolescents ages 1 to 19 were diagnosed with cancer and 1,790 died of the disease. Understanding of cancer prognosis is important.
The most common cancers:
Lymphoma: Fever, weight loss more than 10% body weight in preceding 6 months and drenching night sweats which constitutes the B symptoms, lump in neck, axilla or groin.
Blood cancer: Bleeding manifestations including bleeding gums, bleeding from nose, blood in vomitus,
blood in sputum, blood stained urine, black coloured stools, fever, lump in neck, axilla, or groin, lump in upper abdomen.
Breast cancer survivors who take aspirin regularly may be less likely to die
or have their cancer return. Aspirin has relatively benign adverse effects compared with cancer chemotherapeutic drugs and may also prevent colon cancer, cardiovascular disease, and stroke.
There are a number of cancer symptoms that
men are likely to ignore. These include upset stomach or stomachache; chronic "acid stomach" or feeling full after a small meal; unexplained weight loss; jaundice; wheezing or shortness of breath;
chronic cough or chest pain; frequent fevers or infections; difficulty swallowing; chronic heartburn; swelling of facial features; swollen lymph nodes or lumps on the neck; underarm, or groin, excessive bruising or bleeding that doesn't stop;
weakness and fatigue; rectal bleeding or blood in stool; bowel problems; difficulty urinating or changes in flow; pain or burning during urination; blood in urine or semen; erection problems; pain, aching, or heaviness in the groin, hips, thighs, or abdomen;
testicular swelling or lump; unexplained back pain; scaly or painful nipple or chest, nipple discharge; a sore or skin lump that doesn't heal, becomes crusty, or bleeds easily; and changes in nails.

The vast majority (85%) of cases of lung cancer are due to long-term tobacco smoking. More than half of people with lung cancer die within one year of being diagnosed. The lung cancer five-year survival rate (18%) is lower than many other leading cancer types, such as the colon (65%), breast (90%) and prostate (99%).
The five-year survival rate for lung cancer is 55% for cases detected when the disease is still localized (within the lungs). However, only 16% of lung cancer cases are diagnosed at an early stage.
For distant tumors (spread to other organs) the five-year survival rate is only 4%. Lung cancer occurred in around 1.8 million people globally and resulted in approximate 1.6 million deaths annually.
There are around 415,000 Americans living with lung cancer today, and approximately 158,080 die annually. The age-adjusted death rate for lung cancer is higher for men (51.7 per 100,000 persons) than for women (34.7 per 100,000 persons).
Lung, liver, stomach, colorectal and breast cancers cause the most cancer deaths each year worldwide, accounting for 8.2 million deaths in 2012; about 30% of cancer deaths are due to high body mass index, low fruit and vegetable intake, lack of physical activity, tobacco use, alcohol use.
When cancer cells spread from one organ to another, they are called metastases. Cancer from other organs also may spread to the lungs. When cancer starts in the lungs, it is called lung cancer.
Lung cancer begins in the lungs and may spread to lymph nodes or other organs in the body, such as the brain.
The two main types of lung cancer are small cell lung cancer and non-small cell lung cancer. These categories refer
to what the cancer cells look like under a microscope. Non-small cell lung cancer is more common than small cell lung cancer. People with non-small cell lung cancer can be treated with
surgery (an operation where doctors cut out cancer tissue), chemotherapy (using special medicines to shrink or kill the cancer), radiation therapy (using high-energy rays
(similar to X-rays) to kill the cancer), targeted therapy (using drugs to block the growth and spread of cancer cells), or a combination of these treatments. People with small
cell lung cancer are usually treated with radiation therapy and chemotherapy.
Doctors from different specialties often work together to treat lung cancer. Pulmonologists are doctors who are experts in diseases of the lungs.
Surgeons are doctors who perform operations. Thoracic surgeons
specialize in chest, heart, and lung surgery. Medical oncologists are doctors who treat cancer with medicines. Radiation oncologists are doctors who treat cancers with radiation.
Leukemia, a cancer of the blood cells, not only causes the overproduction of white blood cells,
which help your body fight infection, but also reduces red blood cells, which carry oxygen to all parts of your body.
There are 7.6 million people died of cancer annually - 13% of all deaths worldwide. Lung (1.37 million deaths), stomach (736,000 deaths), liver (695,000 deaths), colorectal/colon (608,000 deaths), breast (458 000 deaths), and cervical cancer (275,000 deaths) caused the most cancer deaths.
The most common types of cancer that kill men are lung, stomach, liver, colorectal and oesophagus and the most common types of cancer that kill women are breast, lung, stomach, colorectal and cervical.
Brain tumor or intracranial neoplasm occurs when abnormal cells form within the brain. There are two main types of tumors: malignant or cancerous tumors and benign tumors.
Cancerous tumors can be divided into primary tumors that start within the brain, and secondary tumors that have spread from somewhere else, known as
brain metastasis tumors. Secondary or metastatic brain tumors are more common than primary brain tumors with about half of metastases coming from lung cancer.
A benign tumor is a mass of cells (tumor) that lacks the ability to invade neighboring tissue or metastasize.
Primary brain tumors occur in around 250,000 people a year globally; there are around 689,000 Americans having brain tumor, and approximately 78,000 people are diagnosed annually.
Brain tumors have the highest per-patient initial cost of care (around $100,000) for any cancer group.
Brain tumors can be deadly, significantly impact quality of life. A tumor is an abnormal mass of tissue that has formed a lump; it’s called a
benign tumor if it grows slowly and is self-limiting. Benign tumors need no treatment, but they can become dangerous if they grow large enough to press on
vital organs, blood vessels or nerves. A malignant or cancerous tumor, is innately dangerous because its cells can divide uncontrollably and produce virtually immortal daughter cells.
On average, in the first few months of 2023, about 450 people in the U.S. have been dying each day of COVID-19, in 2021 roughly 3,200 Americans died each day when the Omicron variant was ripping through the country; however, the daily average of COVID-19 deaths was higher than it was in 12/2022, when roughly 250 Americans were losing their lives each day to the virus.
Since the coronavirus first emerged in Wuhan, China, in 2019, according to data compiled by Johns Hopkins University, it has killed more than 487,000,000 people as of October 2021, and more than 239 million cases have been reported. In September 2021, the U.S. death toll surpassed 700,000, and has continued to
have the highest cumulative number of confirmed cases and deaths globally. India has accounted for about 1 in 3 of all new confirmed cases, and in May 2021 it set records for the number
of new daily deaths with more than 4,500 deaths from COVID-19 reported in a single 24-hour period.
The COVID-19 vaccines were developed and rolled out at record speed, billions of doses have been administered around the world, and studies show most have impressive efficacy. China now leads the world in the number of
vaccine doses given out, though some other nations have vaccinated a greater share of their population.
A study backed by the U.S. Food and Drug Administration (FDA), vaccines for COVID-19 and influenza may slightly increase the risk of strokes caused by
blood clots in the brains of older adults, particularly when these two vaccines are given at the same time to senior who are age 85 and older at the same time.
People with a disability (e.g., asthma, chronic kidney disease, chronic obstructive pulmonary disease, diabetes) are twice as likely to report having long COVID than those without.
These adults have long COVID-19 symptoms, including fatigue, gastrointestinal issues, rapid heartbeat, memory loss, cough, chest pain, skin rashes, difficulty exercising, anxiety, trouble sleeping, depression, trouble focusing, dizziness,
that lasted three months or longer.
The first COVID-19 vaccines began rolling out less than a year into the pandemic. While vaccine development typically has 5 steps
(clinical trials phase 1, phase 2 and phase 3, regulatory approval and manufacturing), and takes one step at a time, which requires 5 years to 15 years to complete, COVID-19 vaccines development has multiple steps happening at once and only takes between 1 year to 2 years for completion.
But the COVID-19 vaccines have been held to the same safety standards as any other vaccine — and rigorous clinical trials have proven that they’re safe and effective.
Pfizer-BioNTech, Moderna,
Johnson & Johnson’s Janssen, and Oxford Astrazeneca were
approved COVID-19 vaccines for use in the US. Studies show that these COVID-19 vaccines are effective at keeping people from getting COVID-19. The other COVID-19 vaccines that do not properly follow the vaccine development procedures, such as
Sinovac and Sinopharm,
were also recommended for emergency use by WHO Strategic Advisory Group of Experts on Immunization (SAGE).
Around 80% of people with coronavirus disease 2019 (COVID-19) recovered without needing any specialist treatment. For these people, this new
coronavirus caused mild or moderate symptoms, such as fever and cough, that clear up in 2 to 3 weeks. For some people, especially older adults
(65 years and older) and people with existing health problems or serious underlying medical conditions (e.g.; chronic lung disease, asthma, heart conditions, cancer, diabetes, renal failure, and liver disease) might be at
higher risk for pneumonia
and death from COVID-19.
Some 86% of people with mild cases of COVID-19 lose their sense of smell and taste but recover it within six months, according to a study of more than 2,500 patients from 18 European hospitals.
Only about 1 in 6 people who get COVID-19, becomes serious ill and develops difficulty breathing, almost all serious consequences of COVID-19 feature pneumonia. As of 5/14/2020, globally there were over 4,437,442 coronavirus cases and around
301,937 deaths. As of 4/20/2021 the number of deaths from COVID-19 has passed 3 million worldwide, according to John Hopkins University; there have been over 141 million confirmed cases since the pandemic began, with the US, India,
and Brazil recording the most infections and over a million deaths between them. The best way to prevent illness is to avoid being exposed to this virus.
During the coronavirus (COVID-19) disease pandemic, some
U.S. healthcare officials advised that Americans should not be walking around with masks in public because they can increase their risk of getting coronavirus by wearing a mask if they are not a health care provider. There is no evidence for the claim
that masks increase users’ risk of catching the coronavirus. The CDC’s written guidance does not suggest that wearing a mask could increase
the risk of catching the virus. A number of Asian countries, such as Japan, South Korea, Taiwan, Hong Kong, Singapore, and Vietnam, where mask use is mandatory, have reported lower levels of COVID-19 infection
than the U.S. had. The reasons have emerged to doubt the wisdom of the guidance, and as a result, after there were over 242,180 coronavirus cases and 5,850+ deaths in the U.S., on April 2, 2020
the CDC revised its guidance that officially advises people to wear masks in public to prevent catching the coronavirus (COVID-19).
A new mysterious, pneumonia-like virus that originated in China in December 2019 spreads through close person-to-person contact. Each infected person seems
to spread the virus to about two others, through coughing or sneezing or by leaving germs on a surface that is touched by non-infected people who touch their faces. Coronaviruses range from the common cold to more-severe diseases such as SARS
and Middle East respiratory syndrome, or MERS. Some coronaviruses, including this new COVID-19, can cause severe symptoms and illnesses, including pneumonia. New COVID-19 illness, patient experienced a range of symptoms including fever
(95%), cough (dried: 67.7% or wet: 33.3%), headache (13.6%), fatigue (less than 10%), sore throat (13.9%), nausea (less than 3%), vomiting (less than 3%), diarrhea (less than 3%) and runny nose (less than 5%). It seems to start with a fever,
followed by a dry cough and then, after a week, leads to shortness of breath (18.6%). In more severe cases, infection can cause pneumonia, severe acute respiratory syndrome, kidney failure and even death.
SARS (Severe Acute Respiratory Syndrome)/SARS coronavirus (SARS-CoV) virus identified in 2003 is thought to be
an animal virus from an as-yet-uncertain animal reservoir, perhaps bats, that spread to other animals (civet cats) and first infected humans in the Guangdong province of southern China in 2002.
Symptoms are influenza-like and include fever, malaise, myalgia, headache, diarrhea, and shivering (rigors). This epidemic of SARS affected 26 countries and resulted in infecting more than 8,000
people and killing nearly 800 in 2003 during the eight-month outbreak. Transmission of SARS-CoV is primarily from person to person. It appears to have occurred mainly during the second week of illness,
which corresponds to the peak of virus excretion in respiratory secretions and stool, and when cases with severe disease start to deteriorate clinically.
Around 60 million people died by the Spanish flu of 1918-’19; as many as
16 million people may have died in India alone.
The Asian flu (H2N2) pandemic of 1957-’58 killed 69,800 people in the US and two million worldwide. Another avian strain (H3N2),
known as the Hong Kong flu, killed 33,800 people in the US and 700,000 worldwide in 1968-’69.
About 300 people around the world were infected by that strain of avian flu (H5N1, also SARS) in 2003 and more than half of them died.
As of July 6, 2009, Novel influenza A (H1N1) has infected 94,512 people and killed 429 in 84 countries,
of which, there were 33,902 cases, 170 deaths in the U.S. There are approximately 226,000 people are hospitalized each year due to seasonal influenza
and 36,000 died in the U.S. As many as 80 million Americans have been infected with H1N1 swine flu, up to 16,000 have been killed and more than 360,000 hospitalized in the U.S. as of 1/15/2010.
The 1918 flu (Influenza Epidemic) pandemic killed 675,000 Americans and 50 million worldwide — some 2 percent of the world’s population at the time; the current state of flu deaths have an estimated 36,000 annually.
In 1748, Jacques Daviel (11 August 1696 – 30 September 1762), a French ophthalmologist, was the first modern European physician to successfully extract cataracts from the eye.
In the 1940s Harold Ridley (10 July 1906 – 25 May 2001), an English ophthalmologist, invented the intraocular lens and pioneered intraocular lens surgery for cataract patients, he introduced the concept of implantation of the intraocular lens which
permitted more efficient and comfortable visual rehabilitation possible after cataract surgery.
Cataracts are most commonly due to aging, but may also occur due to trauma, radiation exposure, be present from birth,
occur following eye surgery, having diabetes, smoking tobacco, or prolonged exposure to sunlight, and alcohol.
About 20 million people globally are blind due to cataracts. Cataract removal/surgery is one of the most common operations performed in the United States.
It also is one of the safest and most effective types of surgery. In about 90 percent of cases, people who have cataract surgery have better vision afterward.
Cataract surgery (or lens replacement surgery) is the removal of the natural lens of the eye (also called "crystalline lens") that has developed an opacification,
which is referred to as a cataract, and its replacement with an intraocular lens. Metabolic changes of the crystalline lens fibers over time lead to the development of the cataract,
causing impairment or loss of vision. During cataract surgery, a patient's cloudy natural cataract lens is removed, either by emulsification in place or by cutting it out.
An artificial intraocular lens (IOL) is implanted in its place. Over 90% of cataract operations are successful in restoring useful vision, with a low complication rate. Day care, high volume, minimally invasive,
small incision phacoemulsification with quick post-op recovery has become the standard of care in cataract surgery all over the world.
The Argus II Retinal Prosthesis System (“Argus II”) is the world’s first approved device intended to restore some functional vision for people suffering from blindness. Argus II is approved for use in the United States and the European Economic Area.
In 2010, there were about 285 million peoplevisually impaired, of whom 39 million were blind; around 82% of people with blindness are over 50 years old and 90% of visually impaired people live in low- and middle-income countries
Early intervention for symptoms associated with autism spectrum disorder is critical
for helping families improve outcomes for their children. Children diagnosed with developmental disorders should be identified as children with special health care needs, and chronic-condition
management should be initiated. Specific autism screenings are recommended at the same time as typical well-child visits from infancy through school age, and at any age thereafter. Developmental surveillance should be performed if concerns are raised about social acceptance,
learning, or behavior. Developmental evaluation is required whenever a child fails to meet any of the following milestones: babbling by 12 months; gesturing (e.g., pointing, waving bye-bye) by 12 months; single words by 16 months; two-word spontaneous (not just echolalic)
phrases by 24 months; loss of any language or social skills at any age.
There is inadequate evidence to recommend an electroencephalogram study in all individuals with autism. Reflecting social communication, ADHD, anxiety, food selectivity, and sleeping disorders could provide
early signs of autism. Eating and sleeping issues can be identified long before autism is diagnosed. Some children with more typical language skills may not be identified until they enter school and social requirements are greater.
Autism is a neurodevelopmental disorder
characterized by impaired social interaction, verbal and
non-verbal communication, and restricted and repetitive behavior. As of 2010 the rate of autism is estimated at about 1–2 per 1,000 people worldwide, and it occurs
four to five times more often in boys than girls; about 1.5% of children in the United States (one in 68) are diagnosed with autism as of 2014, a 30% increase from one in 88 in 2012; around 1 in 100 children in the United Kingdom has
autism in 2014. There is no cure for autism; about 20 to 30 percent of children with autism develop epilepsy by the time they reach adulthood.
Autism spectrum disorder (ASD) is a developmental disorder that affects
communication and behavior. Although autism can be diagnosed at any age, it is said to be a “developmental disorder” because symptoms generally appear in the first two years of life.
About 1 in every 68 U.S. children is affected by a ASD. The causes for this increased incidence are not completely understood though a possible connection to childhood vaccines
(which has been resoundingly rejected by rigorous scientific studies). Although scientists are still trying to understand why some people develop ASD and others don’t, some risk
factors include the child has very low birth weight, a sibling with ASD, older parents, and certain genetic conditions. People with ASD have difficulty with communication and interaction
with other people, restricted interests and repetitive behaviors, and symptoms that hurt the person’s ability to function properly in school, work, and other areas of life.
More than 5 million Americans (3.2 million are women and 1.8 million are men) are living with Alzheimer’s disease, and approximate 500,000 people died each year because of this disease.
Alzheimer’s disease is an irreversible, progressive brain disorder that slowly destroys memory and thinking skills and, eventually, the ability to carry out the simplest tasks. In most people with Alzheimer’s, symptoms first appear in their mid-60s; more than 5 million Americans have Alzheimer’s disease
and around 93,500 people died annually (rank #: 7). The time from diagnosis to death varies — as little as 3 or 4 years if the person is older than 80 when diagnosed to as long as 10 or more years if the person is younger.
Alzheimer's disease is the most common form of dementia, a general term for memory loss and other cognitive abilities serious enough to
interfere with daily life. People with Alzheimer’s have trouble doing everyday things like driving a car, cooking a meal, or paying bills. They may ask the same questions over and over, get lost easily, lose things or put them in odd places, and find even simple things confusing. As the disease progresses, some people become worried, angry, or violent.
One in 9 people over age 65 and nearly half of people over 85 have Alzheimer's disease. Of the 5.4 million Americans with Alzheimer's,
an estimated 5.2 million people are age 65 and older, and approximately 200,000 people are under age 65.
Alzheimer’s disease is the most common cause of dementia among older adults.
Alzheimer's disease and changes in a person's sleeping behavior were linked, people who develop Alzheimer's
show changes in sleep years before their memory begins to decline. Memory problems are typically one of the first signs of Alzheimer’s, though initial symptoms may vary from person to person. A decline in other aspects of thinking, such as finding the right words, vision/spatial issues, and impaired reasoning or judgment,
may also signal the very early stages of Alzheimer’s disease.
Postpartum depression (PPD), also called postnatal depression, is a type of mood disorder associated with
childbirth, which can affect both sexes. Postnatal depression is a type of depression that many parents experience
after having a baby; it's a common problem, affecting more than 1 in every 10 women within a year of giving birth, and one in 20 fathers experienced postnatal depression in the weeks after their child was born. A girl is more at risk of developing mental health problems if her father
has experienced postnatal depression. Symptoms may include extreme sadness, low energy, anxiety, crying episodes, irritability, and changes in sleeping or eating patterns.
Tinnitus is the perception of noise (heard can be soft or loud) or ringing in the ears, and it occurs when there is no outside source of the sounds. It may also sound
like blowing, roaring, buzzing, hissing, humming, whistling, or sizzling. A common problem, tinnitus affects about 1 in 5 people. Almost everyone notices a mild form of tinnitus once in a while. It only lasts a few minutes; however, constant or recurring
tinnitus is stressful and makes it harder to focus or sleep.
Tinnitus is often more noticeable at night because surroundings are quieter. To make tinnitus less irritating, try to relax, get enough rest, and avoid loud places and sounds, and things that
may make tinnitus worse, such as caffeine, alcohol, and smoking. If these are not helpful, it may be a symptom of an underlying condition, such as age-related hearing loss, ear injury, or a circulatory system disorder,
high blood pressure, an allergy, or anemia
(in which the body does not have enough healthy red blood cells). In rare cases, tinnitus is a sign of a serious problem, such as a tumor or
aneurysm. Other risk factors for tinnitus include temporomandibular joint disorder (TMJ), diabetes, thyroid problems, obesity, and head injury.
Urine is made up of excess water and waste products that have been filtered by kidneys from the body. Its natural light yellow color is due to excretion of a pigment found in your blood called urochrome.
If you are healthy, the color should be a pale yellow to gold. Normal urine color varies, depending on how much water you drink. Fluids dilute the yellow pigments in urine, so the more you drink, the clearer your urine looks; when you drink less, the color becomes more dark or yellow. Most people need
to empty their urine up to eight times a day; pregnant women and older people usually have to go more often than others.
If you notice you suddenly have to pee more often than usual, though, it could be a sign of a health problem like a urinary tract infections (UIT), diabetes, an enlarged prostate in men, vaginitis in women,
or a problem with the wall of your bladder called interstitial cystitis.
Bloody urine is common in urinary tract infections (UIT) and kidney stones. These problems usually cause pain; painless bleeding might signal a more-serious problem, such as cancer.
Red or pink urine can be caused by (1) diseases, such as urinary track infections, enlarged prostate, kidney cysts, and kidney or bladder stones; (2) foods, such as beets, blackberries and rhubarb); and (3) medications, such as Rifampin (Rifadin, Rimactane) used to treat tuberculosis, and phenazopyridine
(Pyridium - a drug that numbs urinary tract discomfort), and laxatives containing senna. Red or pink color can also be caused by your long-distance running.
Orange urine can result from medications, such as anti-inflammatory drug sulfasalazine (Azulfidine);
phenazopyridine (Pyridium); some laxatives; and certain chemotherapy drugs. Orange urine along with light-colored stools can indicate the liver disease or bile duct.
If your urine is dark or orange along with pale stools and yellow skin and eyes, your liver might be malfunctioning.
Blue or green urine can be caused by (1) colored food dyes and dyes used for some tests of kidney and bladder function; (2) medications, such as amitriptyline, indomethacin (Indocin, Tivorbex) and propofol (Diprivan); and (3) medical conditions, such as familial
benign hypercalcemia, and UIT caused by pseudomonas bacteria.
Brown urine can result from (1) food, such as fava beans, rhubarb or aloe; (2) medications, such as antimalarial drugs chloroquine and primaquine, antibiotics metronidazole (Flagyl)
and nitrofurantoin (Furadantin), laxatives containing cascara or senna, and methocarbamol — a muscle relaxant; and (3)
medical conditions, such as liver and kidney disorders, kidney damage and urinary tract infections; and extreme exercise that leads to muscle injury.
Cloudy white urine can be caused by urinary tract infections and kidney stones.
Few kidney diseases are known to be caused by direct viral infection of renal parenchymal cells. A kidney infection happens when bacteria or viruses get into kidneys; some kidney-tropic viruses, including the polyomaviruses BK and JC and the herpesvirus CMV, are common in the general population world-wide.
Dialysis fills the vital roles the kidneys play, cleaning the blood of toxins, balancing essential components including electrolytes, keeping blood pressure in check and removing excess fluids. It can be a temporary measure while the kidneys recover, or it can be used long-term if they do not.
Another unknown is whether the kidney damage caused by the virus is permanent.
There are approximately 7,000 different types of rare diseases, with more being discovered each day and disorders; it is estimated that 350 million people worldwide suffer from rare diseases. and approximately 50% of these people are children.
Rare diseases affect nearly 30 million Americans, but they’re difficult to diagnose, and treatment isn't always available, only 5% of rare diseases have FDA approved drug treatment.
Mesothelioma is caused by exposure to asbestos, which is a mineral that was used in the United States. Mesothelioma is diagnosed in approximately 2,500 Americans each year with a
life expectancy of twelve months to eighteen months from the time of diagnosis. There are four types of mesothelioma: pleural, peritoneal,
pericardial, and testicular, which impact the cavity of lung, abdomen, heart and testes, respectively.
Pleural and peritoneal mesothelioma are the most common ones.
Polydipsia is the medical term for extreme thirst, which does not improve no matter how much a person drinks. It is not a disease by itself but can be an important symptom of certain health problems, such as
diabetes. Common diabetes mellitus symptoms include polydipsia, polyuria, extreme and uncontrolled hunger, blurred vision, extreme fatigue or lack of energy, genital itching, slow healing of wounds or cuts, weight change (gain or loss), frequent
or returning infections, and tingling or numbness in the hands or feet.
Syphilis is a sexually transmitted infection that can cause serious health problems if it is not treated. The name for the disease, ‘syphilis’,
originates from an epic Latin poem Syphilis, sive morbus gallicus, ‘Syphilis, or the French disease'. The disease started with genital ulcers, then progressed to a fever, general rash and joint and muscle pains, then weeks or months later were followed by large, painful and foul-smelling abscesses and sores, or pocks, all over the body.
Muscles and bones became painful, especially at night. The sores became ulcers that could eat into bones and destroy the nose, lips and eyes. They often extended into the mouth and throat, and sometimes early death occurred.
Before the introduction of Penicillin in 1943, Syphilis killed 1000's people each year. The first Syphilis epidemic was occurred in Naples, Italy (called ‘Disease of Naples’) in 1495. When Syphilis first surfaced,
the English named it the ‘French disease’, the French called it the ‘Spanish disease’, Germans named it the ‘French evil’, Russians called it ‘Polish disease’, Poles called it ‘Turkish disease’, Turks called it
‘Christian disease’ and Japan called it ‘Chinese pox.’
Arsenic poisoning is a medical condition that occurs due to elevated levels of arsenic in the body. If exposure occurs over a brief period of time symptoms may include
vomiting, abdominal pain, encephalopathy, and watery
diarrhea
that contains blood. Long-term exposure can result in thickening of the skin, darker skin, abdominal pain, diarrhea, heart disease,
and numbness. Arsenic increases the risk of cancer. Exposure is related to skin, lung, liver, and kidney cancer among others.
Depression (major depressive disorder or clinical depression) is a common but serious mood disorder. It causes severe symptoms
that affect how you feel, think, and handle daily activities, such as sleeping, eating, or working. Depression is one of the most common mental disorders that often lead to attempt suicide. 1 out of 6 people in the U.S. succumb
to clinical depression during their lifetime. Experiences with major depressive disorder includes depressed moods, decreased energy, trouble concentrating, lost interest in activities, guilt of feelings of hopelessness, sleep disturbances,
appetite changes and suicidal thoughts or attempts.
A kidney stone is a solid piece of material which is formed in the kidneys from minerals
in urine. Kidney stones typically leave the body in the urine stream, and a small stone may pass without causing symptoms,
otherwise it leads to pain. About 9% of the U.S. population has a kidney stone, and in 2013 about 15,000 deaths globally because of kidney stone disease.
Benlysta is the only treatment on the market specifically for Lupus, a disease in which the body's immune system attacks healthy issue, including skin, joints, kidneys or the brain.

Being diagnosed with HIV does not mean a person will also be diagnosed with AIDS, which is the late stage of HIV infection, when a person’s immune system is
severely damaged and has difficulty fighting diseases and certain cancers. The early symptoms and signs of AIDS include night sweats, prolonged fevers, severe weight loss, persistent diarrhea, skin rash, persistent cough, and shortness of breath.
HIV is spread primarily by having unprotected sex with someone who has HIV; having multiple sex partners; sharing needles, syringes, rinse water, or other equipment used to prepare
illicit drugs for injection; being born to an infected mother, being “stuck” with an HIV-contaminated needle; receiving blood transfusions, blood products, or organ/tissue transplants that
are contaminated with HIV; eating food that has been pre-chewed by an HIV-infected person; being bitten/deeply kissed by a person with HIV; or tattooing or body piercing present a potential risk of HIV transmission.

People suffered from mild hypertension, which is a blood pressure reading of no higher than 160/100 mm Hg, took a 81-milligram tablet of aspirin in the evening had a significant reduction in their blood pressure. Those who took the aspirin in the morning had no reduction at all.
Heart attack, cardiac arrest and stroke generally often occur in early morning hours (between 5:00 AM and 12:00 PM) when the agreeability of thrombocytes is higher. A daily baby aspirin pill (81 mg), often recommended to lower the risks of heart disease,
can also reduce high blood pressure -- but only if it's taken at bedtime.

depression.
Nervous system disorders, diabetes, heart disease and high blood pressure are ones of many physical or medical conditions that contribute to
sexual dysfunction and diminish sexual desire.
Around 5.2 million people in the U.S. do not know they have diabetes. African-Americans and Hispanic-Americans are almost twice as likely to get diabetes as non-Hispanic whites.
Stress symptoms commonly include exhaustion, irritability, muscular tension, inability to concentrate and a variety of physiological reactions, such as sleeplessness, headache and elevated heart rate.
Stress is hurting physical and emotional health and contributing to some of the leading causes of death. Today 1 out of every 4 American are dealing with extremely high stress levels. The top 10
stress factors are money, work, economy, family responsibilities, relationships, personal health concerns, housing costs, job stability, health problems affecting the family, and personal safety.
As of today about 24 million U.S. adults have diabetes, most of them
type-2 diabetes linked strongly with poor diet and lack of exercise. Diabetes was the seventh-leading cause of death in the U.S.,
and is the leading cause of new cases of blindness among adults under age 75, as well as kidney failure, and leg and foot amputations not caused by injury.
The five year survival rate for all
cancers combined is approximately 65 percent.
Surgery,
radiation and
chemotherapy are the forms of cancer treatment.
Lung cancer, a serious illness, is the major cause of death in the U.S. Early screening for this disease is not as effective as it is with
breast,
colon or
prostate cancers. It is also more resistant to treatment than some other cancers.
Palliative care, which helps the gravely ill make the most of the time they have left, provided a surprising bonus for terminal
lung cancer patients. The patients who started soon after their diagnosis on palliative care along with usual cancer care lived nearly three months longer than people given only
standard cancer care. More than half of lung cancer patients have incurable diseases by the time they are diagnosed.
Young people with the kind of irregular heartbeat (known as a trial fibrillation) may be better off undergoing surgery to fix the problem instead of taking medication first.
Diabetes can cause heart disease, kidney failure, limb amputations and blindness
Diabetes occurs when the body is unable to produce or unable to properly use and store glucose (a form of sugar). It is a major risk factor for heart disease. People who are over 40 and overweight are more likely to develop diabetes.
As of 3/2011 more than 25 million Americans have diabetes (more than 90% have Type 2), but an additional 79 million people have pre-diabetes, in which blood sugar levels are higher than normal but not as high as in diabetes.
In 2009 diabetes is the 7th leading cause of death in the U.S. for people aged 25 years and older; 23.6 million people in the U.S. have diabetes; 11.2% of men and 10.2% of women have diabetes.

Both parents’ ages linked to autism risk. When the father was over 40 and the mother under 30, the increased risk was 59 percent greater than for younger men.
By contrast, when the father was over 40 and the mother 30 or older, the risk of autism rose 13 percent.
About 25% of Asian-American adults have hypertension (i.e.; having blood pressure greater than or equal to 140/90 millimeters (mm) mercury (Hg)). Of which there is about 5.0% for the 20–39 age group,
26.5% for the 40–59 age group, and 59.6% for the 60 and over age group. There are around 15.4 million Asian people in the U.S., which primarily comprise persons of Chinese, Asian Indian, Korean, Filipino, Vietnamese, and Japanese descent.
High blood pressure is a risk factor for more than heart disease; left uncontrolled, you may wind up with a disability, a poor quality of life or even a fatal heart attack. High blood pressure can
damage brain, kidneys, eyes, and heart; narrow arteries, cause sexual dysfunction and trouble sleep, and make bone loss.
Having high blood pressure (HBP) and
coronary artery disease (CAD) puts you at a greater risk of a
heart attack or
stroke. You can have HBP for years without knowing it because HBP itself usually has no symptoms. If your blood pressure rises and stays high over time, it can damage your
heart,
blood vessels,
kidneys, and other parts of your body. The numbers in a blood pressure reading include Systolic and
Diastolic. Systolic (the top number) is the maximum pressure in the arteries when the heart is contracting or squeezing. Diastolic (the bottom number) represents the pressure in the
arteries when the heart is at rest. The recommended blood pressure goal is below 140/90 mmHg (millimeters of mercury). If your blood pressure is above that level, you may have HBP. The most common of medications to treat HBP in people who have CAD is
Beta-blockers, which slow the heart rate, reduce the heart's output of blood, and decrease the force of the heart beat.
There are 30 different blood types. However, most people have blood types: O, A, B and AB. Type O blood is the most common, it can help other Os and also people with AB, A and B blood types.
The next common one is type A, which can help other As and also people with AB blood types. Type B is one of the rarest blood types, it can help people with B, O, A and AB blood types.
Type AB is the rarest blood type of 4 common ones, it can help people with AB, O, B and A blood types. The major common blood types in the U.S. include O+: 37.4%; O-: 6.6%; A+: 35.7%; A-: 6.3%; B+ 8.5%; B-: 1.5%; AB+: 3.4% and AB-: 0.6%.
A new report released on November 10, 2010 by the CDC found that around 49.9 million Americans aged 18-64 went at least part
of the last twelve months without health care insurance coverage.
People who lost their jobs between September 1, 2008 and December 31, 2009 can keep COBRA coverage under their former employer's plan for up to 18 months.
The economic-stimulus plan
provides a 65% subsidy for COBRA (Consolidated Omnibus Budget Reconciliation Act) premiums for up to 9 months for people who were laid off during this period

If you have no insurance and/or your family has a low income, you and your family are eligible for joining the Partnership for Prescription Assistance (pparx.com), a
coalition of pharmaceutical companies, healthcare providers, and patient advocacy groups that helps patients get free or discounted medications. Typically, as a member you can receive free medications or pays only $4 for a generic thyroid prescription.
If you've ever been hospitalized, do not make any decisions before you have received, and analyzed, all the bills. Once you've determined what you can afford, ask the hospital's credit officer for interest-free payments. If
the debt is truly unwieldy, ask for the Medicare rate (not the insurance rate) or a charity write-off.
In 2008, an estimated 57 million people died throughout the world. Of 1000 people died, 159 would have come from high-income countries, 677 from middle-income countries and 163 from low-income countries.
In 2008, cardiovascular (schaemic heart) diseases killed 7.3 million people worldwide, of which 6.2 million from stroke or another form of cerebrovascular disease.
Throughout the world in 2008, more than 8 million deaths were among children under five years of age, and 99% of them were in low- and middle-income countries.
The U.S. has fewer practicing physicians per capita than many similarly large
and wealthy countries with health care systems. The country has only 2.6 physicians per 1,000 people, which lags behind comparable countries, Austria (5.2), Switzerland (4.3), Germany (4.3), Sweden (4.1), Italy (4.0), Spain (3.9),Australia (3.7), Netherlands (3.2),
France (3.2), Belgium (3.1), United Kingdom (2.8) and Canada (2.7). However, the U.S. has slightly more licensed nurses, 17.5 per 1000 people, relative to comparable countries, it just lags behind South Korea (20.5), Sweden (19.7) and Belgium (18).
U.S.
hospitals have more employees than most comparable countries, but many are administrative workers; the country has 20.1 hospital employees (per 1,000 people), of which 9.5 handling administrative work, it's just behind Switzerland,
which has 25 hospital workers (per 1,000 people), of which 7.6 doing administrative jobs.
As of March 2019, there are 1,005,295 physicians
in the U.S., of which 479,856 are primary care doctors and 525,439 are specialist physicians; California has the largest number of physicians (112,906), and North Dakota has the lowest number (2,015).
Dr. Daniel Hale Williams (January 18, 1856 – August 4, 1931) was the first African American general surgeon, who in 1893 performed the first documented, successful
pericardium surgery in the United States to repair a wound. A pericardial window is a cardiac surgical procedure to create a fistula –
or "window" – from the pericardial space to the pleural cavity to allow a pericardial effusion
(usually malignant) to drain from the space surrounding the heart into the chest cavity – where the fluid is not as dangerous; an untreated pericardial effusion can lead to cardiac tamponade and death.
Graduated from Northwestern University Medical School, Dr. Williams opened a private practice where his patients were white and black. Black doctors, however, were not allowed to work in American hospitals at that time;
as a result, in 1891, Dr. Williams founded the Provident Hospital and training school for nurses in Chicago, IL. Dr. Henry Dalton was the first American to
successfully perform pericardium surgery to repair a wound. Earlier successful surgeries to drain the pericardium, by performing a pericardiostomy were done by
Dr. Francisco Romero in 1801 and Dr. Dominique Jean Larrey in 1810.
Medical Billing Advocates of America, a group that helps patients handle medical bills, and Time Magazineanalyzed hundreds of bills from hospitals and revealed many overcharges on a patient’s itemized bill. For example, a Tylenol pill for $15, $53 for per pair of gloves, $8 for a grocery bag (to hold your personal items), $8 for a box of tissues, $53 for per non-sterile pair (sterile are higher), $10 for a plastic cup used to administer medicine, $23 for per alcohol swab, $17.50 for a color mark on the body for surgery, $20 for a blood pressure measurement,
$6.25 for a nurse to hand you medicine taken by mouth per instance, and $93.50 for cost of use of overhead light in operating room.
Hospital list prices aren't completely irrelevant; however, as they usually serve as a starting point for negotiations with commercial payers. Hospital charges are essentially their list prices for medical services, which are different from the actual amount of money insurers, patients or the government ends up paying hospitals in exchange for the services.
The prices on a hospital's chargemaster bear little relationship to the amount most patients are asked to pay. That's because commercial insurers or government (e.g.; Medicare, Medicaid) negotiate discounts with healthcare providers on behalf of their members, and the costs are often less than the actual cost of care.
Hospitals' rising list prices primarily affect the uninsured and people with coverage but who seek care at hospitals outside of their insurance network. Many hospitals often allow low-income patients who are uninsured to receive free care or care for a reduced charge.
If you don’t have coverage in 2014 you’ll have to pay a fee. In 2014 it’s $95 per adult ($47.50 per child) or 1% of income, whichever is higher. The family max is $285.
If you have coverage and want to explore Marketplace plans, you can. But if you have an offer of insurance from an employer, you may not be able to get lower costs on Marketplace insurance based on your income. It depends on whether the insurance you’re offered is considered affordable and meets minimum standards.
Medicare isn’t part of the Marketplace. If you have Medicare, keep it.

Pre-eclampsia is a sometimes deadly condition of pregnancy marked by high blood pressure and protein in the urine. Often when a mother has pre-eclampsia, the baby needs to be delivered prematurely to save the lives of mother and baby.
Women as they get into their 40s may also have some hypertension already, and if they do, they have a higher risk of that being exacerbated during pregnancy.
Morning Fasting Blood Glucose for Diabetics
Insulin is a hormone produced by the
pancreas to control
blood sugar (Glucose).
Diabetes can be caused by too little insulin, resistance to insulin, or both.
Glucose is vital to the human body because it's an important source of energy for the cells that make up muscles and tissues. Chronic diabetes conditions include
type 1 diabetes and
type 2 diabetes.
When there is too much glucose in blood, it is classified as type 1 diabetes. When blood sugar levels are higher than normal, but not high enough to be classified as type 1 diabetes, it is called type 2 diabetes. After many years, diabetes can cause many serious problems, such as eye problems
(which may lead to blind), foot/leg problems (which may be removed), heart attack, stroke, pain, tingling, loss of feeling, nerve damage, which causes digesting food problems, weakness, erection issues, and kidney damage.
Hypertension, or high blood pressure (HBP), has no noticeable symptoms.
Having HBP and coronary artery disease (CAD) puts you at a greater risk of a
heart attack or
stroke. You can have HBP for years without knowing it because HBP itself usually
has no symptoms. If your blood pressure rises and stays high over time, it can damage your
heart,
blood vessels,
kidneys, and other parts of your body. The numbers in a blood pressure reading
include Systolic and
Diastolic. Systolic (the top number) is the maximum pressure in the arteries when the heart is contracting or squeezing. Diastolic (the bottom number) represents the pressure in the
arteries when the heart is at rest. The recommended blood pressure goal is below 140/90 mmHg (millimeters of mercury). If your blood pressure is above that level, you may have HBP.
The most common of medications to treat HBP in people who have CAD is
Beta-blockers, which slow the heart rate, reduce the heart's output of blood, and decrease the force of the heart beat.
There are many different medicines that can be used to treat high blood pressure; these include Alpha blockers, Angiotensin-converting enzyme inhibitors, Angiotensin receptor blockers, Beta-blockers, Calcium channel blockers, Central alpha agonists, Diuretics, Renin inhibitors, including aliskiren (Tekturna), and Vasodilators.
There are about 100 prescribed medications for high blood pressure.
1. Stroke/Carotid Artery Ultrasound Test - Carotid ultrasound shows whether a waxy substance called plaque (plak) has built up in your carotid arteries. The buildup of plaque in the carotid arteries is called carotid artery disease.
The ultrasound test identifies plaque buildup in the carotid arteries, which is a leading cause of stroke.
2. Abdominal Aortic Aneurysm Ultrasound - An aneurysm
(AN-u-rism) is a balloon-like bulge in an artery. Arteries are blood vessels that carry oxygen-rich blood to your body. The ultrasound
test checks for aneurysms in the abdomen. The danger lies in the risk of the aneurysm bursting or rupturing.
3. Electrocardiogram (EKG) - An electrocardiogram (e-lek-tro-KAR-de-o-gram), also called an EKG or ECG, is a simple, painless test that records the heart's electrical activity, which may predict pending heart attack.
4. Peripheral Arterial Disease (P.A.D.) Test - Peripheral arterial disease (P.A.D.) is a disease in which plaque (plak) builds up in the arteries that carry blood to your head, organs, and limbs.
Leg cramps due to poor circulation could indicate something more serious. This screening measures the extremities for peripheral arterial disease.
5. Harding of the Arteries (ASI) Test - The Arterial Stiffness Index (ASI) measures the flexibility or hardening of the arteries. The
stiffer the arteries, the harder the heart has to work and the more long-term damage it will sustain.
B. Ultrasound of the Heart
Echocardiogram Ultrasound Test - Echocardiography (EK-o-kar-de-OG-rah-fee), or echo, is a painless test that uses sound waves to create moving pictures of your heart.
The pictures show the size and shape of your heart. They also show how well your heart's chambers and valves are working.. This ultrasound test is done to evaluate the valves and chambers of the heart in a noninvasive way and may detect enlargement
of the heart, valve abnormalities, blood clots, tumors and more.
C. Major Heart Tests
1. Physical Stress Test - Stress test provides information about how your heart works during physical stress.
It is used to determine the amount of stress that your heart can manage before developing either an abnormal rhythm or evidence of ischemia (not enough blood flow to the heart muscle).
2. Nuclear Stress Test (also called as "Cardiolyte" or "Thallium" or "Adenosine") - Nuclear stress test measures blood flow to your heart muscle both at rest and during stress on the heart.
It's performed similarly to a routine exercise stress test, but provides images that can show areas of low blood flow through the heart and areas of damaged heart muscle
Repeat colonoscopies within 10 years of a first test
Early imaging for most back pain
Brain scans for patients who fainted but didn't have seizures
Antibiotics for mild- to-moderate sinusitis unless symptoms last for seven or more days or worsen
Stress cardiac imaging or advanced non-invasive imaging in the initial evaluation of patients without cardiac symptoms unless high-risk markers are present
PAP smears on women younger than 21 or who have had a hysterectomy for a non-cancer disease
Advanced imaging or bone scans in patients with early-stage breast or low-grade prostate cancer
Bone scan screening for osteoporosis in women younger than 65 or men younger than 70 with no risk factors
Routine cancer screening on dialysis patients with limited life expectancies

There are more than 100 different types of cancer, but they all are a group of diseases of body's cells. When
normal cells lose their ability to limit and grow disorderly, their tissues will be produced too much
and tumors begin to form. Tumors can be either benign or malignant. Benign tumors are not cancer; malignant tumors are cancer. The signs of cancer may include:
Change in bladder or bowel habits;
A sore that does not heal;
Unusual bleeding;
Thickening or lump in the breast or elsewhere;
Indigestion or difficulty swallowing;
Obvious change in a mole or wart;
Nagging cough or hoarseness.
These signs can be caused by cancer or by other problems. It's important to see a doctor if any of these symptoms lasts over 15 days. Don't wait for symptoms to become painful; pain is not an early sign of cancer.
Breast pain can be a symptom of cancer. Different people have different symptoms of breast cancer. Some people do not have any signs or symptoms at all.
Some warning signs of breast cancer are:
New lump in the breast or underarm (armpit).
Thickening or swelling of part of the breast.
Irritation or dimpling of breast skin.
Redness or flaky skin in the nipple area or the breast.
Pulling in of the nipple or pain in the nipple area.
Nipple discharge other than breast milk, including blood.
Any change in the size or the shape of the breast.
Pain in any area of the breast.
Keep in mind that these symptoms can happen with other conditions that are not cancer.
Pancreatic cancer is seldom detected at its early stages when it's most curable. This is because it often doesn't cause symptoms until after it has spread to other organs. Its early warning signs of pancreatic cancer may include:
Abdominal pain that radiates to your back
Loss of appetite or unintended weight loss
Yellowing of your skin and the whites of your eyes (jaundice)
Light-colored stools
Dark-colored urine
Itchy skin
New diagnosis of diabetes or existing diabetes that's becoming more difficult to control
Lightheadedness and shortness of breath without or without chest discomfort.
Discomfort in other areas of the body; symptoms can include pain, numbness, tingling or discomfort in one or both arms (especially the left one), jaw, neck, stomach, back, nausea and/or vomiting.
(Women are more likely than men to have neck and shoulder pain along with other symptoms).
Chest discomfort or pain that is crushing or squeezing in the center of the chest that lasts more than a few minutes, or squeezing or feels like a heavy weight on the chest, or this goes away and comes back. It can feel like uncomfortable pressure, squeezing, fullness or pain.
Fact action can save lives; don't wait more than five minutes to call 911.
Posterior circulations strokes occurs when a blood vessel in the back part of the brain is
blocked causing the death of brain cells, the warning signs may include:
Sudden numbness or weakness in the face, arm, or leg, especially on one side of the body.
Sudden confusion, trouble speaking, or difficulty understanding speech.
Sudden trouble seeing in one or both eyes, double vision or other vision problems.
Sudden trouble walking, dizziness, loss of balance, or lack of coordination.
Ulcerative colitis is a form of colitis, a disease of the colon (large intestine), that includes characteristic ulcers, or open sores. The main symptom of active disease is usually constant diarrhea mixed with blood, of gradual onset. The signs of cancer may include:
Cramping and Abdominal Pain;
Bloody Stool;
Urgency;
Sleep Interruption;
Weight Loss;
Dehydration;
Frequency of Symptoms.
These signs can be caused by ulcerative colitis or by other problems. It's important to see a doctor if any of these symptoms occurs frequently. Don't wait for symptoms to become painful.
Warning Signs of Lung Disease
Early signs of lung disease are easy to overlook. The signs and symptoms can differ by the type of lung disease. Common signs are:
Lack of usual level of energy
Trouble breathing
Shortness of breath
Feeling like not getting enough air
Decreased ability to exercise
A cough that won't go away
Coughing up blood or mucus
Pain or discomfort when breathing in or out
Make sure to call your doctor if you have any of these symptoms.
Make sure to consult with your doctor if you have one or more these signs to prevent an asthma attack that happens when your airways narrow, which makes it hard for you to breathe in air, after being irritated.
There are four reliable COVID-19 vaccines, Pfizer/BioNTech, Moderna, AstraZeneca/Oxford, and Johnson & Johnson (Janssen), which are widely recognized in the world.
The effectiveness of these vaccines is varied ranging from 70% to 95%:
You may have side effects after having one of these vaccine injections, one or both doses. Most side effects of these vaccines have been minor. When side effects occur,
they typically last just a few days. This may be an enhanced reaction as the body is building immunity. Common side effects include:
Fatigue
Headache
Fever
Muscle aches
Chills
Nausea and vomiting
Pain or redness at the injection site
Painful, swollen lymph nodes in the arm where the vaccine was injected
If you have body aches, fever, fatigue, chills, and/or headaches, you may treat with fluids, rest, and take the following medicines (as needed): Tylenol (acetaminophen), Advil,
Motrin (ibuprofen), Aleve (naproxen sodium) or Aspirin.
If you have redness, itching, warmth at the injection site, you may be considered a mild allergic reaction, and you may treat with antihistamines, such as Benadryl (diphenhydramine),
Allegra (fexofenadine), Claritin (loratadine) Zyrtec (cetirizine) or topical steroid creams like cortizone.
If side effects last more than 72 hours, contact your doctor. It takes up to 2 weeks for the vaccine to be fully effective.
The coronary heart disease is the leading cause of death in the U.S. According to the CDC,
About 600,000 people die of heart disease in the United States every year–that’s 1 in every 4 deaths.
