Fairly safe procedur: Colonoscopy is a very safe and essential procedure , complications are rare but do occur, some bleeding is possible after biopsy . All of the doctor are well trained , ask your pcp , or someone who had it to recommend you rather than walking into a place you do not know.Procedure can not cause cancer.

Colonoscopy: Colonoscopy by an incompetent doctor cannot cause colon cancer although it could have missed colon cancer. If a hole was put in the colon then there could be severe infection. Recommend reviewing your results of the colonoscopy because polyps, hemorrhoids, colitis, and diverticulosis could all cause rectal bleeding.
