Colorectal cancer is the third most common cancer in the United States, affecting men and women. The most common type of colorectal cancer is adenocarcinoma, which begins in cells that create mucus to lubricate the colon and rectum.

Colorectal cancer is found in the colon or rectum (large intestine) and usually begins with growths called polyps found on the inner lining of the colon or rectum.
