Call your wife and get her to ask the nurse to look on her chart and see if there is a record of them having done a CA-125 on her Monday.
If the tests, scans, and the CA-125 indicates O.C., she should be scheduled to see an oncologist, not a surgeon. Nothing against surgeons, but trust me, that's who she should be seeing.
About 16 years ago, I began to learn more than I'd like to know about O.C. Won't go into details.
