Colorectal cancer is malignant cells found in the colon or rectum. The colon and the rectum are parts of the large intestine, which is part of the digestive system. Because colon cancer and rectal cancers have many features in common, they are sometimes referred to together as colorectal cancer. Cancerous tumors found in the colon or rectum also may spread to other parts of the body.
Gross Anatomy. The colon is a 5-6âft long, U-shaped part of the large intestine (lower gastrointestinal tract). By definition, the cecum (and appendix) and ano-rectum, which are parts of the large intestine, are not included in the colon. Embryologically, the colon develops partly from the midgut (ascending colon to proximal transverse colon) and partly from the hind gut (distal transverse colon to sigmoid colon).
