	Feature Article Cancer Definition Cancer is the uncontrolled growth of abnormal cells in the body. Cancerous cells are also called malignant cells. Alternative Names Carcinoma; Malignant tumor 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. Cancer appears to occur when the growth of cells in the body is out of control and cells divide too rapidly. It can also occur when cells “forget” how to die. There are many different kinds of cancers. Cancer can develop in almost any organ or tissue, such as the lung, colon, breast, skin, bones, or nerve tissue. There are multiple causes of cancers, including: Radiation Sunlight Tobacco Certain viruses Benzene Certain poisonous mushrooms and aflatoxins (a poison produced by organisms that can grow on peanut plants) However, the cause of many cancers remains unknown. The most common cause of cancer-related death is lung cancer. The three most common cancers in men in the United States are prostate cancer, lung cancer, and colon cancer. In women in the U.S., the three most frequently occurring cancers are breast cancer, lung cancer, and colon cancer. Certain cancers are more common in particular geographic areas. For example, in Japan, there are many cases of gastric cancer, while in the U.S. this type of cancer is relatively rare. Continue reading this article

Breast cancer (8 images) Average Rating: (Doctor-Reviewed information)
Breast cancer is a cancer that starts in the tissues of the breast. There are two main types of breast cancer: Ductal carcinoma starts in the tubes (ducts) that move milk from the breast to the nipple. Most breast cancers are of this type; Lobular carcinoma starts in parts of the breast, called lobules, that produce milk. In rare cases, breast cancer can start in other areas of the breast. Many breast cancers are sensitive to the hormone estrogen. This means that estrogen causes the breast cancer tumor to grow. Such cancer is called estrogen receptor positive cancer or ER positive cancer. Some women have what's called HER2-positive breast cancer. HER2 refers to a gene that helps cells grow, divide, and repair themselves. When cells have too many copies of this gene, cells - including cancer cells - grow faster. Experts think that women with HER2-positive breast cancer have a more aggressive disease and a higher risk of recurrence than those who do not have this type.
