Hello. So glad to hear from you. My drs never mentioned to me anything about an estrogen blocker but I'm going to ask. I was told to stay away from hormone treatment being in menopause. As to the mri. I got one directly after my operations but again there was no mention re ct scans and radiation. I know the mri are much more difficult to get approved thru my health insurance so we resort to ct scans every three months. It is challenging to know the right questions to ask ...
