As you most likely know cancer is a very mysterious and deadly disease, but what is cancer really? Cancer is a disease which forms when abnormal cells divide without control. These cells are able to invade other tissues. There are over one hundred different types of cancer. Each different type of cancer is classified by the type of cell that is initially affected. Although there are many great advancements of technology to treat and prevent cancer, cancer is still the number one leading cause of death for people under the age of eighty five. In fact, in the United States, one out of every four people die from cancer. Cancer is a very complicated disease which has not yet been fully understood. When the abnormal cells divide without control they form lumps or masses of tissue known as tumors (except in the case of leukemia where cancer prohibits nomal blood function by abnormal cell division in the blood stream). When we are born we have normal cells that continually grow until adulthood. We also have abnormal cells in our body. As we get older our normal cells stop dividing and only divide to replace dead or damaged cells. The abnormal cells in our body continue to divide even into adulthood and form cancerous cells. Most cancers develop into tumors, although all tumors are not created in the body by the abnormal cells. Tumors that are not created by abnormal cells are not cancerous. These tumors will not affect the body in as harmful ways as cancerous tumors would. These non cancerous tumors are known as benign tumors. Cancer has many possible causes because it is a complex group of diseases. Some forms of cancer can run in your family. You can inherit a gene of cancer but even if it is inherited it does not mean you will get cancer. A genetic alternative that is linked to cancer is just a risk factor. Another cause of cancer is the use or exposure of carcinogens. Tobacco, asbestos, compounds in a car exhaust fumes, arsenic, the sun, and radiation such as gamma and x-rays. When our bodies are exposed to these substances, free radicals are formed that try to steal electrons from other molecules in the body. These free radicals damage cells and affect their ability to function normally. These products contain over seven thousand different chemicals and of these chemicals, sixty are known to cause cancer. Eighty seven percent of lung cancer deaths and thirty percent of all cancer deaths are caused by smoking. Exposure to too much sun can also cause cancer and ultraviolet radiation from the sun or a tanning bed causes the cells to grow abnormally and out of control. Another cause is obesity. In fact, the American Cancer Society Prevention II showed significant increases in cancer occurrence in people who are most overweight. There are many different cancer treatments but the three most common are surgery, chemotherapy, and radiation. Surgery is normally the first option of treatment if the tumor can be removed from the body. Sometimes only parts of the tumor can be removed. Chemotherapy uses drugs to kill cancer cells. Doctors enter the medicine through an IV or the patient can take the medicine by mouth. The drugs travel through the body in the bloodstream, reaching cancer cells that have spread from the tumor to any other parts of the body. Radiation therapy kills the cancer cells or shrinks the tumor by using high energy rays. There are two different types of radiation therapy known as external or internal radiation. External radiation is painless but side effects may occur. Internal radiation is from radioactive material put into the tumor. Cancer is not yet curable, the phrase "cure for cancer" is nonsense; there will not be any single cure for cancer because there…

Prostate and Endometrial Cancer
Prostate cancer is a cancer that forms in the tissues of the prostate, the gland of the male reproductive system, which is found below the bladder and in front of the rectum. This cancer usually occurs in older men. In the United States there are estimated 241,740 new cases and 28,170 deaths in 2012.
The cause of prostate cancer is unknown. Prostate cancer is thought to be related…

In today's society, the second leading cause of death in the United States is Cancer. Cancer is one of the scariest topics that affect thousands of Americans daily. According to "Top Five Most Dangerous Cancers In Men And Women (Infographic)" (July, 2014), the expected amount of new cases in America, to be diagnosed with Cancer in 2014 was 1,665,540 (UnityPoint Health, 2015). In addition, the predicted amount of Americans…

Cancer is a disease that is usually very bad. The word cancer comes is the Latin word for crab. Cancerous growths act something like a crab, pinching healthy tissue as they grow. Although there are many kinds of cancer, they all start because of out-of-control growth of abnormal cells. Normal body cells grow, divide, and die in an orderly fashion. During the early years of a person's life, normal cells divide more…
developing breast cancer in women is up to 3 times higher if the mother or sister suffered before.
Some breast cancers are linked to a specific genetic mutation which, incidentally, is more common in certain ethnic groups and in some families. According to statistics, the likelihood of developing breast cancer among women who have this mutation is between 80% and 90%
The real truth is that these risk factors are responsible for only a fifth or sixth of cancers. 80 or 85 % of cancers are actually…
Cancer is the uncontrolled growth of abnormal cells in the body. Cancerous cells are also called malignant cells.
Causes, Incidence, and Risk factors
Cells are the building blocks of living things.
Cancer grows out of normal cells in the body. Normal cells multiply when the body needs them, and die when the body doesn't need them. Cancer appears to occur when the growth of cells in the body is out of control and cells divide too quickly. It can also occur when cells forget how to die.…
Cancer, a six letter word that can change your world. Do you know what Cancer is? Are you even aware of the symptoms? Cancer can change and turn your lives inside out, however this type of sickness that runs throughout your body is a silent type of disease. There is one thing in mind and that is to have faith. Cancer concerns many Americans throughout the world it can be preventable with the right knowledge of our white coat doctor’s and through our faith that everything will turn out for the best…
I’m going to solve is the cancer conspiracy in the U.S. The cure for cancer has been suppressed and hidden from the public since the 1800’s to present day. Some individuals, companies and government organizations are involved in suppressing information about treatments to keep their multi-billion dollar industry thriving. A massive conspiracy to hide perhaps the greatest cure known to mankind can be solved
To understand the cancer conspiracy one most first understand cancer and what causes it and the…

Mr. Andre I would like to give an insight about the diagnosis you have just been diagnosed with. I hope it gives you a better understanding and helps you with the type of stage you have and if any treatment can be successful for you. I hope you can come to an option and go back to doing as you have done with your…
focus on the topic of breast cancer because multiple members of my family have been diagnosed with this type of cancer. I wanted to research breast cancer due to the fact that there are a large number of women in my family. A number of people in my family have passed due to different types of cancer. Breast cancer, being the most common, I would like to be informed on the signs and symptoms due to the risk that anyone of us could be diagnosed with this type of cancer.
