Cancer, colon

Other names: Colorectal cancer


Colon Cancer is Cancer of the large intestine (colon), the lower part of your digestive system. Rectal cancer is Cancer of the last several inches of the colon. Together, they're often referred to as colorectal Cancers. Most cases of colon Cancer begin as small, noncancerous (benign) clumps of cells called adenomatous polyps. Over time some of these polyps become colon Cancers. Polyps may be small and produce few, if any, symptoms. For this reason, doctors recommend regular screening tests to help prevent colon Cancer by identifying polyps before they become colon Cancer.



In most cases, it's not clear what causes colon Cancer. Doctors know that colon Cancer occurs when healthy cells in the colon become altered. Healthy cells grow and divide in an orderly way to keep your body functioning normally. But when a cell is damaged and becomes Cancerous, cells continue to divide — even when new cells aren't needed.


Factors that may increase your risk of colon Cancer include older age, African-American race, personal history of colorectal Cancer or polyps, inflammatory intestinal conditions, inherited syndromes that increase colon Cancer risk, family history of colon Cancer and Colon polyps, low-fiber high-fat diet, sedentary lifestyle, Diabetes, obesity, smoking, alcohol use, and radiation therapy for Cancer.

To reduce your risk of colon Cancer make lifestyle changes such as eating a healthy diet rich in fruits and vegetables, drinking alcohol in moderation if at all, stopping smoking, exercising regularly, and maintaining a healthy weight.
