Im guessing CT or MRI scans would give an image of the ovaries, check for cysts etc. Blood tests can keep an eye on tumour markers, but I dont think they are 100% accurate.
Good luck to both of you, sounds like you both need it.
Im having the same thing happen too me..took a lot of questions as too why this is happening and still feel so disappointed that no one can give me definite answers to my questions. They completely took my right ovary out 2 years after having a partial hysterectomy. i have a 6.4 cm cyst on my left ovary that they are trying too shrink before thinking about surgery because if i do go ahead with the surgery i will lose part of my bowel and may cause damage too my bladder as the ovary sits partially on it too. Basically my insides and a total mess with no ending as of yet in sight. I hope you are getting better answers too your questions then i am right now. Goodluck.
