While it is well known that colorectal cancer screening has enormous potential to substantially reduce the incidence of colorectal cancer, how to do so in an optimal way remains elusive. Many questions about proper processes, who to screen, when to stop screening, and what defines the proper interval for screening have not been adequately studied. Two articles in this issue of the Archives indicate that there is much room for improvement in the way we measure proper utilization of screening colonoscopy, ensure adequate follow-up, and evaluate net benefit among those who screen positive.
