Honestly those ovaries are producing the goodies the cancer needs to thrive so if there are any cells bloody left there they will use it. Zoladex will put you in complete menopause. (And think about this ...How many women fall pregnant whilst breast feeding and no periods?) I say bring it on...then whip the damn things out. Also I believe with zoladex you can have a AI instead of tamoxifen which most likely your oncologist plans on you having. But .....ask him/her why they think this is the best option. I hadn't had a period fir 2.5 years and they still checked I was completely through menopause before starting a AI.
