Question
Dear Dr. C,
I am a very healthy 50 year old male and recently had a colonoscopy as a part of a routine physical. I had a couple of diverticuli, no polyps or other abnormalities and have absolutely no history of c/r cancer in my family. I know there is quite a lot of variation regarding how often this procedure should be repeated; I've heard as soon as 5 years and as long as 10 years (or never). Which theory do you subscribe to? Thank you very much for your thoughts.

Answer
Woody,
80% of patients who develop colorectal cancer have no family history or high-risk factors.  While there is some variation in recommendations, most colorectal cancer specialists and a number of gastroenterogical, surgical, and cancer societies recommend colonoscopic screening every 5 years after the age of 50 for average risk people.  People with moderate or high risk should be screened more often.
