Bilateral cysts and elevated ca-125

My 39 y/o sister has severe back pain for 3 years. She recently found out that she has an elevated CA-125 of 120 and bilateral ovarian cysts. She lives in a small town and they referred her to the closest University for a laparoscopy. I’m afraid the university will do a knee jerk hysterectomy while doing the lap. Is this a valid concern?
What should she and I know to avoid this.
I’m a med student and know nothing but believe she may have corpus luteal cysts or endometriosis because pain seems to be worse the last 14 days of every cycle. We have no history of cancer in our family. I don’t understand why she has such pain to her back unless she has adhesions in the pouch of douglas perhaps? Have you heard of severe back pain where the patient rolls on the floor and is awaken from sleep.

Dear Flymacmamma-
Elective surgical procedures are performed based on informed consent..if you sister does not sign for a hysterectomy or removal of her ovaries, neither should be done at that time.

We have seen many patients with back pain as a symptom…it is often directly associated with pathology in the pelvis impinging on nerves in that area. If your sisters cysts are large or located toward the back of her pelvis, they could be pressing on the low back area, creating this pain, especially after hours of sleeping when there is little movement or change in position.
She should have surgery to remove the cysts, but preserving her ovaries if the condition is deemed benign. Good luck.
