Hi @SlimTee,
I had the same as you and it’s a shock with tough decisions to make.
I had been on HRT for many years before my DCIS of 17mm and IDC of 7mm was diagnosed, E & P positive HER2 negative. My GP who gave me my biopsy results said to stop HRT instantly which I did. I had no drastic side effects just menopause symptoms, that became gradually more noticeable after about 3wks, they can’t be avoided but weren’t too bad, for me.
After surgery, luckily no chemo just radiation followed by Aromatase Inhibitors. Hot flushes worse than expected now and GP monitoring calcium levels but better than cancer returning, I think. If you’ve been told no more HRT I doubt your GP will give you any more prescriptions as your body would use the eostrogen to make more cancer cells. Arm yourself with all the facts from your surgeon and oncologist then talk it over with your breast care nurse or family. Menopause isn’t pleasant but neither would more cancer be.
Wishing you all the best, R
