Cancer of the colon and the rectum (also known as colon cancer or colo-rectal cancer) is a malignant growth arising from the inner lining of the colon or rectum. Colo-rectal cancer is a major cause of cancer-related deaths among men and women in the United States. The good news is that colo-rectal cancer is both curable and preventable if it is detected early and completely removed before the cancerous cells metastasize (spread) to other parts of the body. Colo-rectal cancer can be prevented by removing colo-rectal polyps before they grow and change into cancers, or by using natural substances or man-made chemicals to prevent the colo-rectal polyps from changing into cancer. (Using natural substances or chemicals to prevent cancer is called chemo-prevention). Measures to prevent diseases usually fall into one of five categories of safety and effectiveness. These categories are:
What measures to prevent colo-rectal cancer have proven effectiveness and long term
safety? Most colo-rectal cancers arise from colo-rectal polyps (small growths on the inner lining of the colon and the rectum). Even though colo-rectal polyps are initially benign, they can grow and change into colo-rectal cancers over a period of time ranging from five to twenty years. A large study that was conducted in several research centers in the United States showed that patients who had their polyps removed (usually via colonoscopy) had a 90% decrease in colo-rectal cancer.
