Louise Walter, MD and colleagues from Dartmouth published a study in the Journal of the American Geriatrics Society.  They studies adults 65+ who underwent colonoscopy screening, surveillance of prior polyps and evaluation of symptoms. They found the highest incidence of colorectal cancer was among those undergoing diagnostic examinations (2.4%). The incidence of advanced polyps increased with patient age from 65–69 to ≥85 years for screening (7.1% to 13.6%; p = 0.05) and surveillance (9.4% to 12.0%; p < 0.001). In patients without any significant findings on colonoscopy, 61.9% aged 75–79 years, 39.1% aged 80–84 years, and 27.4% aged ≥85 years were told to continue colonoscopy.
