Cancer most frequently occurs in the rectum, and less commonly in the sigmoid, cecum, and the hepatic or splenic flexures of the transverse colon. Macroscopically, ulcerated and ulcerinfiltrative forms are observed, as well as nodular tumors (polypoid and large-tubular). Signet-ring Cell carcinoma also occurs, while Squamous Cell Carcinoma, both keratinizing and non-keratinizing, is found in the anal region. Complications include Hemorrhage, bowel perforation leading to Peritonitis or paraproctitis, intestinal obstruction, and fistulae formation.
