I received a call from my Gp today I am due for the CA125 test tomorrow and also a MRI scan in 2 weeks so they can get a better look, for what I presume may be surgery?
Thanks for you answer.
Welcome to the community. I am sorry you are dealing with this. The ultrasound techs generally don't say much because the doctor is supposed to explain to the patient. At least that is how it typically works here in the U.S.
The odds are very much in your favor because most ovarian cysts are benign (non-cancerous). Functional / simple cysts resolve on their own, typically in 2 to 3 cycles. And some complex cysts do too. Of course with this one being 8cm and "not a simple cyst" that probably won't happen. The characteristics that are more concerning for malignancy are multiple and/or thick septations and irregular borders. There are a number of ovarian cysts that are not simple that are always benign and appear black on imaging (and can have some white or gray areas) such as hemorrhagic (blood-filled), dermoid (mature teratoma), and endometrioma.
If surgery is needed, it is best to have just the cyst removed (cystectomy) and not the ovary. Not all surgeons have good cystectomy skills so you will want to make sure the surgeon does a lot of cystectomies. I don't know about where you live, but here in the U.S. far too many women lose an ovary or ovaries when it is unnecessary. Removal of even one ovary (or any part of the "reproductive" system) can impair fertility as well as negatively impact long-term health. The ovaries of women who have all their parts (uterus, both ovaries and tubes) produce hormones their whole lives which are essential to every aspect of health and well-being.
I hope this helps. Please keep us posted.
