Intestinal cancers may develop as a result of prolonged or severe inflammation. This includes: Colorectal cancer has a prevalence of 7% at 30 years after diagnosis and accounts for 15% of deaths in people with Crohn's. Risk is higher if the disease occurs in most of the colon. Endoscopic surveillance is performed to detect and remove polyps, while surgery is required for dysplasia beyond the mucosal surface. Small bowel cancer has a prevalence of 1.6%, at least 12-times greater in people with Crohn's disease. Unlike colorectal cancer, endoscopic surveillance is ineffective and not recommended for small bowel cancer.
