Colorectal polyp growth ‘triples risk of advanced histology’

Findings support colonoscopic resection of polyps that increased in size, say US doctors.

Small colorectal polyps that grow at follow-up screening are three times more likely to have advanced histology than stable or regressing polyps, show results from the largest longitudinal study of its kind.

US doctors suggest this risk was greater still — 25-fold higher — for small polyps that doubled in volume per year compared to polyps that did not meet this threshold.
