JAMA 4 2026 Colorectal Cancer and Mortality Risk Among Older Adults With vs Without Adenoma on Prior Colonoscopy

This study investigated whether older adults who previously had benign growths called adenomas were at a higher risk for developing colorectal cancer compared to those with clear past screenings. While the research confirmed that a history of adenomas does slightly increase the likelihood of future malignancy, the overall risk of cancer death remains remarkably low for patients over the age of 75. Crucially, the data revealed that these individuals are significantly more likely to die from other health conditionsthan from colon cancer, regardless of their physical frailty. Consequently, the authors suggest that elderly patients should prioritize other medical concerns over continued invasive colonoscopy surveillance, as the procedure's benefits are often outweighed by competing mortality risks.
