Patients with IBD are more prone to the development of malignancy. Persons with Crohn disease have a higher rate of small bowel malignancy. Patients with pancolitis, particularly ulcerative colitis, are at a higher risk of developing colonic malignancy after 8-10 years of disease. The current standard of practice is to screen patients with colonoscopy at 1-2 year intervals once they have had the disease for greater than 10 years.
