Editor's Note
The longer time a screening colonoscopy takes, the less risk of developing cancer within 5 years, this study finds.
Patients whose screenings were performed by physicians whose average colonoscopy times lasted less than 6 minutes were twice as likely to develop colon cancer within 5 years as those whose colonoscopy times averaged more than 6 minutes.
A colonoscopy time beyond 8 minutes added no extra reduction in cancer risk.
