Single screening sigmoidoscopy linked to lower colorectal cancer risk two decades later

AI Summary

A study from Norway indicates that undergoing a single screening sigmoidoscopy is linked to a lower risk of colorectal cancer two decades later. The long-term benefits of screening underscore its importance in early detection.

A randomized controlled trial of adults in Norway found that a single screening sigmoidoscopy led to a sustained reduction in colorectal cancer (CRC) incidence for more than two decades after screening, with women seeing a more modest risk reduction than men.
