6 years ago I had a molar pregnancy. About a year ago, I was diagnosed with CKD, Stage 2 due to high blood pressure. I was placed on blood pressure medications and my birth control was changed by OBGYN. Fast forward a year later, and I now have 2 large cysts on one ovary, and 1 large of 119mm cyst on the other. CBC, CMP are all pretty normal ranges. But, my CA19-9 level is slightly elevated. I'm in the waiting period to go have the cysts surgically removed, and have a tubal ligation, but what does this CA19-9 mean?
