Hi Moomin,
The way it's been described to us from our specialists is that you shouldn't feel any different between zoladex and oophorectomy. They both achieve exactly the same thing. If you are not planning on having more children and don't mind (that much) the operation, then an oophorectomy is more practical since you avoid the hassle of the injections.
One thing to note though is that you should make sure you check your estrogen levels (via a simple blood test) to make sure zoladex is indeed suppressing them adequately. There is a small % of women where zoladex may not fully work, so it's worth double-checking for peace of mind.
Hi Moomin
It's Emily here from Breast Cancer Care.
While you're waiting for replies on here, I wanted to let you know that we have a telephone volunteer who had Zoladex who then went onto have an oopherectomy (removal of ovaries).
If you'd like me to arrange a phone call with them, feel free to ring me on 0345 077 1893 and I'll put you in touch.
Best wishes
Emily at Breast Cancer Care
