I believe anyone in your position would be anxious and worried even without the family history. It might be worth discussing seeing a genetic counsellor regardless of outcome so you know your risks. First thing you do is start mapping family tree with those who have had any cancer and ages diagnosed (or approx). It helps to know that background and determines if appropriate for testing or not.
I have met a couple of women with your condition who have had surgery and no further issues. However the whole surgical process and waiting was very traumatic for them.
I hope things move rapidly for you so you have a treatment plan soon. Kath x
