Hello doctor, actually my mom having problem in colon. She have to go to toilet 10 times in a day and she feel weightless of 6-7 kg in last 2 months. I have checked with gastro doctor they have done colonoscopy and give us a biopsy for examination. They advised for a ct scan so please tell me that can I do a ct scan of abdomen with 16 slice ct scan machine or with any better slice. And please tell me how many % cancer chances are there if found a biopsy in colon.
