Hi @SlimTee, I was 50 when I was diagnosed, stage 2, grade 3 IDC with 1 lymph node involved. My treatment was lumpectomy, chemo, radiation, hormone blockers. I wasn't in menopause when I started this journey, so can't help with the HRT question, but I did have a mirena which both my surgeon and oncologist wanted removed before I started treatment. They'll want to stop anything that may interfere or conflict with your treatment. The early days of diagnosis is very overwhelming as a lot of decisions need to be taken very quickly, but this group is great for support and advice, and there are lots of people here doing through the same journey.
Best of luck with your treatment, and don't be afraid to ask lots of questions.
