serous borderline tumor

I had to have my uterus taken out when I was 29 years old in 1979 due to a severe prolapse, and other issues with it. The doctor left both ovaries and tubes. I've had some ongoing pain in the left ovary area for the past four years. I finally found a gyn that ordered a transvaginal and abdominal US. I had a 2.3 cm cyst on the ovary. He decided due to my age (at that time 65 yrs old) he needed to take the ovaries and tubes out. I went back in 2 weeks later for my pre-op visit, and he'd changed his mind. He decided to just watch it for awhile. I was not happy with his decision. I went to 5 doctors over the next year and a half before one decided watching had gone on long enough. The cyst was now 5.6 cm. I had surgery Dec. 14, 2016 to remove the left ovary/cyst and tube. The preliminary pathology report said they didn't know what it was. They sent everything to MD Anderson. My gyn called about three weeks later to tell me it was a serous borderline tumor, and sent me to a gyn oncologist. The gyn oncologist classed it as a 2A. She did surgery Feb. 22, 2017  to remove the right ovary, tube, and numerous biopsies.There was one area in the omentum she said looked malignant, but the preliminary pathology report said it wasn't. The pathology report while I was in surgery said all was fine. All the other biopsied areas are doing fine, but THAT area is still most painful. Does anyone know if this is anything to be concerned about?  Two days later I got a call saying the final pathology report shows serous borderline tumor cells are all in the omentum, and I am now a stag 3A. I will have my post-op appointment this week.

They will be keeping a close eye on it. She said a SBT isn't normal cells, nor is it true malignant cells, but it can turn malignant, that is the reason for them to closely monitor it for the rest of my life.
