I wanted to post an update. My CA-125 test results were normal, so that's a huge relief! It was 17.9, and I guess below 35 is considered normal. It's not a complete "whew!" since I know the test does seem to be imprecise, but it certainly makes me feel better about things.
I still have an appt. with an oncologist gynecologist on Monday to get another opinion on how best to proceed.
