Are there symptoms of colon polyps?

Not typically. On occasion, polyps may infarct, twist on their stalk, bleed, or secrete (villous tumors of the rectum) with resulting "diarrhea." however, most polyps & colon cancers are identified (hopefully) before symptoms develop. Early detection at a smaller polyp size means higher cure rates, lower risk of malignant transformation or invasion, & improved survival before cancer develops. Get a colonoscopy!
