First seen Mar 11, 2026 · Last updated Apr 25, 2026 · Updated 10 times

Summary

This study tested a new laser-based measuring tool (AccuMeasure) to see if it measures colon polyps more accurately than the usual methods (eyeballing or using biopsy forceps). Accurate polyp size is important because it helps doctors decide how often patients need follow-up colonoscopies to catch cancer early. The study involved 138 adults scheduled for colonoscopy and compared the laser measurements to those taken by doctors and pathologists.
