There are several harmful diseases found in this world, some in which can be cured, some that have treatments and others that have been killing people for years now. Cancer, for example, is the name for a category of various diseases in which the characteristics and functions are changed in the body cells. Cancer is defined as the unwanted growth of cells who invade normal tissues and organs and eventually spread throughout the body. Although there are many kinds of cancer, all cancers harm the body when damaged cells divide uncontrollably to form lumps or abnormal growth of tissue called tumors. Tumors can grow and impede with various systems in the human body such as the nervous, circulatory, and digestive systems and can also release hormones that alter body function. Right behind heart disease, cancer …show more content…
Most foods contain various kinds of fat, some being healthier than others. Some fats found in foods from plants and animals are known as dietary fats in which contain different types of fatty acids, such as saturated, monounsaturated, and polyunsaturated. Saturated fats (butter, coconut oil, dairy products, meat) are found in animal products and processed foods. They are usually solids making them not heart healthy, since they are mostly know for raising one’s LDL cholesterol (low density lipoprotein). Polyunsaturated fats (corn oils, sunflower oil, soybean oil) are mostly found in plant sources and they tend to lower blood cholesterol levels. Monounsaturated fats (olive oil, peanut oil, canola oil, sesame oil) however, are found in both plant and animal products. These fats can help reduce the “bad” cholesterol, lowering LDL cholesterol. Thus, polyunsaturated and monounsaturated fats have the most positive effect in one’s health, while saturated fats have the most negative effect. The dietary fats are risky and can possibly lead to the development of
Cardiovascular disease has become an increasingly significant issue in many countries as it is the leading cause of death for the whole human population. According to World Health Organization, ischemic heart disease had caused about 7 million people to lose their life in 2011. One of the most common cardiovascular illnesses is myocardial infarction. It is defined as the death of cardiac myocytes due to complete blockage of a coronary artery. t-PA is a thrombolytic drug that used to treat myocardial infarction by dissolving the thrombus that causes the occlusion.
In this lecture, it talks about fat and how it affects us and our bodies. There are two main different types of fat, saturated and unsaturated. Many types of saturated fat are found in meat and dairy products. These fats are hard to break down for cells, because of this, they tend to get tucked away and build up over time if worked off. Unsaturated fats are found in olive oil and other plant oils. These types of fat are readily consumed for energy.
Cardiomyopathy is a disease of the heart muscle, causing the heart muscle to become enlarged, thick or rigid. In rare cases, the muscle tissue in the heart is replaced with scar tissue.
Cancer is the term used to describe a group of diseases consisting of hundreds of ailments and although there exists so many different types of cancer, they all begin in a similar way. The body is made up of over a trillion cells, and cancer is the uncontrolled growth of malfunctioning cells in the body (Dawson, 1996). “Normal body cells grow, divide, and die in an orderly fashion. During the early years of a person’s life, normal cells divide faster to allow the person to grow. After the person becomes an adult, most cells divide only to replace worn-out or dying cells or to repair injuries” (American Cancer Society, 2012).
In general, the word cancer is the name given to a collection of related diseases (What is cancer? n.d.. ). In our everyday life multiple thousands of your cells divide in order to keep the function of that certain cell ongoing. Through out all types of cancer, the body begins to force cells to divide without cease which then spreads to the surrounding tissue. Cancer can take form in any part of the human body, were thousands of cells are cancerous. Through time human cells grow and divide to form new ones as it is a requirement for the body to keep functioning. Therefore
There are many reasons I have used health care services at different times in my lifetime from birth to the present time. I have utilized pregnancy healthcare services. I have used health care services for preventive care such as a yearly Pap smear or health physicals. My friends, family and my co-workers may use health care services for the same reasons as mine, especially if they are of the same gender.
Cancer is a condition in the body when there is uncontrolled growth of abnormal cells that evolve into tumors. Fatty food, smoking, and drinking all affect the chances of developing cancer. Treatments for cancer include, but are not limited to, Surgery, radiation, and chemotherapy. Anyone can become a victim of cancer, but we can decrease our chances of getting cancer by being more informed on the disease and how to prevent it.
Just as breast cancer is killing our African American women, heart disease is also one of the major diseases killing our women. Heart disease is one of the nation’s leading causes of death in both woman and men. About 600,000 people die of heart disease in the United States (Americas heart disease burden, 2013). Some facts about heart disease are every year about 935,000 Americans have a heart attack. Of these, 610,000 are a first heart attack victim. 325,000 happen in people who have already had a heart attack. Also coronary heart disease alone costs the United States $108.9 billion each year. This total includes the cost of health care services, medications, and loss of productivity. Deaths of heart disease in the United States back in 2008 killed about 24.5% of African Americans.
Heart disease is the leading cause of death worldwide. (social inequality, 2009). Heart disease is a structural or functional abnormality of the heart, or the blood vessel supplying the heart, that impairs its functioning. (free dictionary). Heart disease is also known as cardiovascular disease. Since there are many conditions related with heart disease. The most common types are coronary artery disease or damage in the heart’s major blood vessels, stroke or damage to the brain from interruption of its blood supply, and high blood pressure or a condition in which the force of the blood against the artery walls in too high. These conditions may lead to a heart attack. (mayo).
(Slide 2) What is Cardiomyopathy? If we break down the word we can see “Cardio” which means of the heart, “myo” which means muscle, and “pathy” which means disease, therefore cardiomyopathies are diseases of the heart muscle. (Slide 3) There are 3 main types of cardiomyopathies; hypertrophic, dilated, and restrictive. I will only be discussing dilated cardiomyopathy, which is characterized by the enlargement of the hearts chambers with impaired systolic function. It is estimated that as many as 1 of 500 adults may have this condition. Dilated cardiomyopathy is more common in blacks than in whites and in males than in females. It is the most common form of cardiomyopathy in children and it can occur at any age (CDC).
The omega-3 fatty acids, popularly referred to as fish oil, are considered unsaturated fats. Science differentiates between unsaturated and saturated fats quite clearly. One fact that separates the two is the temperature at which melting occurs. Saturated fats melt at a higher temperature than unsaturated fats. The science behind fatty acids is rather complex; carboxylic acids with long hydrocarbon chains are the building blocks of saturated and unsaturated fats. This is important to the human body for many reasons; one reason being unsaturated fats do not cause plaque build-up in arteries like saturated fats due to their molecular structure in the human blood stream.
Cancer is a disease that affects human somatic cells. It causes the cells to divide uncontrollably and form masses known as tumors. There are two different types of cancer tumors. Some tumors are benign and other tumors are malignant. Benign tumors look similar to the tissues that they came from and develop slowly. The tumor remains in the same area that the tumor originated in. Malignant tumors are formed from cells that do not resemble the tissue that they came from. They vary in shape and size. This enables pieces of the tumor to break off and spread to other places in the body. Over the past few decades cancer has become a very prominent disease. There are many different types of cancer and many different causes for the the disease. Most cancers are because of a genetic mutation. The most common type occur when a cell is dividing. Proto-oncogenes, which are alleles in a normal cells, mutate to form oncogenes. These oncogenes cause cancer because they do not allow the cells to self destruct or become epistatic. There have been several research projects which have been testing epistatis.
Cancer is a general term for a large group of diseases that can affect any part of the body; it is caused by mutations to the original genetic code. Cancer, in its simplest explanation, is the uncontrolled growth of cells within the body resulting in the accumulation of large masses of cells, commonly known as tumours.
Control fats! “Bad fats” such as the trans-fats found in most takeaway meals, processed foods, margarines, biscuits, and snack & fried foods should be avoided. These increase the risk of heart, stroke, and other “killer” diseases. “Good fats” include mono-unsaturated fats as found in nuts, walnuts, avocados, seeds, fatty fish and flaxseed, and hence strongly recommended.
Saturated fats come from animal sources like steak, hamburger and pork. Unsaturated fats are derived from plants. There are also trans fats that are considered poison for the body. They raise the bad cholesterol in your body, and should never be included in a healthy diet. There are also fatty acids like omega-3 and omega-6 that are good for a healthy body.
