having uc or crohn’s disease increases the risk of developing colorectal cancer but most people (more than 90%) with inflammatory bowel disease don’t develop cancer. the american cancer society recommends that people with uc and crohn’s have a screening colonoscopy eight years after diagnosis if the entire large intestine is involved and 12 to 15 years after diagnosis if only the left part of it is affected. follow-up colonoscopy screening should occur every one to two years after that.
