To the Editor: In their study of the risk of colorectal cancer (CRC), Dr Singh and colleagues1 conclude that in persons who undergo a colonoscopy during which no neoplastic lesions are identified, “the risk of developing CRC is at most 60% to 70% of the risk of developing CRC in the general population,” although the size of risk reduction “may not be as great as previously suspected.”
