Colorectal cancer is a disease in which malignant (cancer) cells form in the tissues of the colon or the rectum. Colorectal cancer (sometimes called Colon Cancer) is the 2nd leading cause of death from cancer in the U.S.

Surgery is the most common treatment for all stages of colon cancer. Treatment typically involves one of the following types of surgery. A local excision (for early stages of colorectal cancer) involves placing a tube through the rectum into the colon to cut out the cancer. If the cancer is found in a polyp (a small bulging piece of tissue), the operation is called a polypectomy. If the cancer is larger, your doctor may perform a partial colectomy (removing the cancer and a small amount of healthy tissue around it).
