I'm sorry you are dealing with this. Since the cyst isn't that large, are they monitering it for now to see if it resolves so you don't needlessly undergo surgery?
If it continues growing and surgery is needed, why is the other ovary being removed? Most ovarian cysts, even complex ones after menopause, are benign. A frozen section can be done during surgery to check for malignancy. Removal of ovaries as late as age 75 is associated with earlier mortality since ovaries produce health-promoting hormones a woman's whole life. As far as the adhesions - Did you have a hysterectomy?
Keep us posted.
How are you doing? Did you end up having surgery?
