Expected long-term impact of the German screening colonoscopy programme on colorectal cancer prevention: Analyses based on 4,407,971 screening colonoscopies

Despite modest participation rates, the German screening colonoscopy programme will lead to substantial reductions in the CRC burden. The reductions will be fully disclosed in the long run only and predominantly affect numbers of incident cases above 75 years of age. Screening offers would need to start at younger ages in order to achieve more effective CRC prevention at younger ages.
