I had my first colonoscopy last week. Two polyps were removed and 1 precancerous polyp was removed. Dr. called week later saying two polyps okay; howver, other larger one was precancerous. He has to schedule another colonoscopy @ 6 weeks from now because he wants to make sure he got the entire polyp. Biopsy criteria showed that he may not have gone deep enough. The remaining tissue/polyp, is that precancerous since it is part of polyp removed? I am @ 65, female
