Prior data from Canada suggest that colonoscopy does not reduce right proximal colon cancer incidence and mortality (JW Gastroenterol Feb 20 2009). To investigate this issue further, researchers in Germany conducted a population-based, case-control study involving 1688 patients ≥30 with a first diagnosis of invasive primary colorectal cancer (CRC) and 1932 controls randomly selected from population registries.
