What are the symptoms of colonic 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!

Often none: Polyps are generally asymptomatic, that's why we do colonoscopy for screening.

None: Colon polyps are generally asymptomatic which is why routine screening is recommended at age 50 (or earlier with a family history). Rarely polyps can bleed or be large enough to cause obstruction.
