Hi, I recently had my first colonsocopy, at age 54. There were no internal problems with the colon, but the doctor said there is a bulge inward on the colon wall, from outside. What could that be? I am male, white, 6 tall, 160 lbs, and don t smoke or drink much. Physically very active as a rancher. I feel fine. I take no medications. They want to do a CT scan now to look at the area, which is okay but I don t want to get too far ahead of things. So who has an idea of what could cause the bulge? Thank you
