Given that you do not have any known risk factors, it is recommended that you have your first colonoscopy at age _____ years.

Colorectal cancer risk greatly increases starting at about age 50 years plus. If a colonoscopy does not find any problems another one will not be needed for 10 years, unless symptoms arise that indicate the need for a colonoscopy.
