Hi, (Colonoscopy) I was told immediately after waking up in recovery room, no polyps no growths, everyting looked clear and clean.......if there is a polyp or some type of growth that is not suppose to be there, a biopsy in order, the results could be anywhere from 4-7 days. Depending on when the Dr. can read them and get back to you. Same for my endoscopy, in which mine tured out to be gastritis and I was diag. with H. Pylori bacteria. Hope this helps!
