Yes , but you will probably be switched to an AI. You body can convert fat tissue and I think "cholesterol "?? Or something like that into hormones

@AmyMoffit is correct. No more Tamoxifen now you will take the AI inhibitors. I was given the choice of having my ovaries removed and was told I would be on these.

I had one years ago and yes they still gave me tamioxfen

Adrenal glands also produce estrogen

I had a total hysterectomy years ago I take tamoxifen but initially i took femara, after five years on the femara i was switched to tamoxifen
