Assessing Colorectal Cancer and Mortality Risk in Older Adults

Colonoscopy is one of the most effective cancer prevention interventions developed in the last half-century. The long-term protective effect of colonoscopy has been validated in many well-designed studies. For individuals of screening age, a colonoscopy without adenomas reflects a lower risk of incident and fatal colorectal cancer (CRC) for at least 10 years and potentially up to 20 years.
