For example, individuals with Crohn's disease involving the small bowel are at higher risk for small intestinal cancer. [85] Similarly, people with Crohn's colitis have a relative risk of 5.6 for developing colon cancer. [86] Screening for colon cancer with colonoscopy is recommended for anyone who has had Crohn's colitis for at least eight ...
