Yield from colonoscopic screening in people with a strong family history of common colorectal cancer

Abstract

Background and Aims: People with a strong family history of common (so-called 'sporadic') colorectal cancer are generally advised to undergo colonoscopic screening, but the starting age for this is unclear.
