I lost a friend to Ovarian cancer because they were concentrating on intestinal issues. She worked for a wonderful Doctor but he missed it also. I don't remember if she had a CT scan for stomach problems. My guess would be that she didn't until it was too late. A pelvic CT scan should be done with all intestinal problems. The blood test for ovarian cancer is not always accurate but it will give more false positives than negatives. Most Doctor don't put a lot of faith in it alone.
