AbstractColorectal cancer is one of the leading causes of cancer-related morbidity and mortality. Colorectal cancer commonly develops slowly via adenomatous polyps, a process usually requiring ≥ 10 years. This allows for early detection. Endoscopic polypectomy and surgery of early disease can reduce the incidence and mortality of colorectal cancer. Both hemoccult testing and colonoscopy are the most widely used tests for colorectal cancer screening; however, colonoscopy has the highest sensitivity for colorectal neoplasia. Sigmoidoscopy is not commonly used for screening in Germany. Colon contrast enema is no longer recommended for screening. As colonoscopy serves as a diagnostic and therapeutic tool and is the reference method in hemoccult and sigmoidoscopy studies, it is viewed as the gold standard for the diagnosis of colonic disease. New methods including capsule colonoscopy and virtual colonoscopy have great potential but are currently not recommended for early detection of colonic neoplasia.
