Oh dear @gobilly that sounds awful. I am on tamoxifen too. I did have hot flushes initially but seems to have settled for me. Now I am gaining weight so have to try new tactics to manage that. My cancer was aggressive too. I don't know about hormones but I would be getting a list of all the questions and reservations you have for discussion with the doctor. You need to understand all the risks and benefits. You can always ask for a second opinion too. I am sorry this is happening for you. It would be a worry and you need to be sure of your decision going forward. Best wishes
