If you carry a BRAC 1 or 2 faulty gene then yes it would most definitely assist but not elimate the risk of ovarian cancer.
If you are pre menopause and would like to change to an aramatose inhibitor then that can be an option or have ovaries knocked out with drugs or radiotherapy is another. This needs to be discussed with your oncologist or breast surgeon.
You would need a referral to an onco-gynacologist to discuss all risks and appropriate surgery. We can be quick to say ...take it all...but knowing real risks and risk reduction surgery that is really necessary is best to discuss with appropriate specialists. A genetic referral to discuss risk factors is enlightening and certainly reduced my anxiety after testing gene negative.
