Cancer
The organs and tissues of the body are made up of tiny building blocks called cells. Cancer is a disease of these cells. Cells in different parts of the body may look and work differently but most reproduce themselves in the same way.
Cells are constantly becoming old and dying, and new cells are produced to replace them. Normally, cells divide in an orderly and controlled manner. If for some reason the process gets out of control, the cells carry on dividing, developing into a lump which is called a tumour.
Cancer is a term for diseases in which abnormal cells divide without control and can invade other tissues. Cancer cells can spread to other parts of the body through the blood and lymph systems.

Lung cancer is the leading cause of cancer deaths in both women and men in the United States and throughout the world. Lung cancer has surpassed breast cancer as the leading cause of cancer deaths in women.
In the United States in 2007, 160,390 people were projected to die from lung cancer, which is more than the number of deaths from colorectal, breast, and prostate cancer combined.
Only about 2% of those diagnosed with lung cancer that has spread to other areas of the body are alive five years after the diagnosis, although the survival rates for lung cancers diagnosed at a very early stage are higher, with approximately 49% surviving for five years or longer.
Some lung tumors are metastatic from cancers elsewhere in the body. The lungs are a common site for metastasis. If this is the case, the cancer is… Read More

Cancer occurs when something goes wrong with this system, causing uncontrolled cell division and growth. Colon cancer is cancer of the large intestine (colon), the lower part of your digestive system. Most cases of colon cancer begin as small, noncancerous (benign) clumps of cells called adenomatous polyps. Rectal cancer is cancer of the last 6 inches of the colon. Together, they’re often referred to as colorectal cancers.
Colorectal cancer is the second most common cancer killer overall and third most common cause of cancer-related death in the United States in both males and females. Who is at risk for colorectal cancer. Men tend to get colorectal cancer at an earlier age than women, but women live longer so they catch up with men and thus the total number of cases in men and women is equal. Women diagnosed with uterine or ovarian cancer before age 50… Read More
