Hi kittykatster and welcome to the forum. I am SO Sorry to see you join the club that no-one every thought they'd be joining 🙁
You've found the right spot here tho, for support & info from those who've 'been there, done that'! So hopefully we'll be able to smooth the way for your own story. Make sure you take a trusted friend or family member with you to your appointments, as a 'backup set of ears', as it is difficult remembering everything that is said. Also, consider recording your sessions on your phone, so you can go over it again later, for the same reason. 😉
Mine was ILC - I was lucky to only have the one lumpectomy, rads & tablets .... and have recently finished with the tabs now! I had a BC 'scare' about 20+ years ago, when I was on HRT cream. It also had testosterone in it. The testosterone had made my breasts go very lumpy & I also went off it cold turkey. It was not fun.
Re going off HRT .... was it your GP, Onc or Surgeon who advised you to go off HRT? There has been a lot of discussion recently, that HRT isn't considered the 'bogeyman' that it once was, so start with your Onc first, I reckon, as they are the ones that will be dealing with your meds prescriptions re hormones etc.
What are the symptoms that you expect to experience when you go off it?
Hot Flushes, depression, sleeplessness, aches & pains .....
Check out this info, re a patch that is available to reduce both hot flushes and the need to pee - ask your Onc about it. .... You might even be able to cut the patch in half & use a smaller dose, if the smaller dose works for you! :)

Check out these podcasts - many of them refer to HRT & cancer .... and suggest natural remedies that can help. (Do 'control F' & search for 'HRT' to find HRT specific topics.)

Don't forget - you can whack up ANY question - remember there are NO dumb questions!!! This diagnosis can really muck with your brain too - so if you feel sad, angry, distressed .... ask your GP (or your treating team) for a referral to see a counsellor .... or ring our Helpline here on 1800 500 258 (Mon-Fri 9-5) for a confidential chat.
I'd suggest you also listen to Charlotte Tottman's podcast (link below).
She is a BC specialist counsellor who was diagnosed herself, and had a double mastectomy, so knows EXACTLY what we've all been thru, both emotionally and physically! Her own reaction to her diagnosis was also quite different to what she 'thought' it might be, given that she'd been counseling women's reactions for some years before, so thought she 'new' what to expect! She is VERY easy to listen to, too xx
