Hi @nicmaree, so happy to hear that your op went fine and that the medical team were very supportive <3. I think that is probably the most important part of your treatment done!
It seems natural to me that you should be so tired. You're doing really well to keep up with the exercises and the small walk each day. Self-care and a little indulgence too is just the ticket.
My mother had breast cancer (2 occurrences, over a decade apart) and my sister and I were told it wasn't genetic, I think that was because of mum's age - but then I turned up at almost 55 with two cancers, one in each breast. So I've been referred for genetic testing.
But I also was on low dose HRT a few years, and went through a lot of stress last year. Then I thought, did I have too many glasses of wine with my dinner over the years....there's so many things to suspect. I realise it can be helpful sometimes to know why, but I've decided not to worry about it anymore, unless of course there is genetic information turned up. Especially I don't want to blame myself, or anyone else. I'm just focussing on getting better and a future with a new perspective <3 :)
You will find lots of support on here, such a lovely group of people :) <3
