Hello, Yes, I recently had a colonoscopy done. This is my 2nd in 5 years. This time they took biopsies. I don t remember having biopsies taken the first time. So is it routine, do they need to ask permission. I remember it being very painful, I saw it being done on the screen. My Doctor says the results will not be in for about 2 months. What knowledge can be gained from a biopsy? Thank-You
