Are Polyps of the Colon Premalignant?

Abstract

The theoretical ferment over whether colonic polyps become malignant often boils down to a practical question: Should polyps beyond the reach of the sigmoidoscope be biopsied? In Dr. Behringer's opinion, they should be if the surgical risk is not too great. Dr. Prohaska feels that in some cases if two colon contrast studies show a polyp unchanged in size and location, the risk of surgery may exceed the threat of malignancy.
