Polyps are removed from colon for biopsy, during the internal examination of colon. This done by colonoscopy or sigmoidoscopy. Sedatives are given to patient, during this procedure, so that the patient does not feel any pain or discomfort. The only aftereffect from this procedure is flatulence and minor wind pain caused by air insufflation into the colon during the procedure.
