The findings of a randomized phase III clinical trial reveal the long-term benefits of screening, involving a single flexible sigmoidoscopy examination. In a cohort of 170,034 individuals, sigmoidoscopy was found to confer a 26% reduction in the risk of colorectal cancer (CRC), in addition to a 30% reduction in the risk of CRC-related mortality at a median follow-up duration of 17.1 years. These findings demonstrate the prolonged long-term benefits of a one-off sigmoidoscopy examination.
