Hi, sorry to hear you are having a rough time. I was diagnosed last December, had my surgery then 8 weeks of radiation before starting on tamoxifen. My oncologist advised me to have the Mirena removed so I did. My surgeon said she didn't think it mattered one way or another. I'm 54 and that was my 2nd Mirena which I had as part of treatment for endo. Lucky for me I think I went through menopause while I had the Mirena. I'd had some hot flushes but nothing horrendous. Since being on Tamoxfen I get hot flushes from time to time and the only other thing I've noticed is I have put on a little bit of weight I am finding hard to shift - just a couple of kilos. Just had my first full check up and everything is fine. Like lots of things, there seems to be different views on what's best. My view is listen to who you trust and do what feels right for you. Good luck. Hope things settle down for you.
