Hi @Theresa9,
I'm so sorry for your diagnosis, I too find myself in a similar situation although I've decided for no reconstruction.
I also have the "dense" breast tissue, but was never warned that I was more likely to get breast cancer especially if I used HRT (which I did)
Anyway no use thinking I wish I'd known, it is what it is and you need to let yourself gently come to terms with it and understand that a lot can be done, they are much more advanced in this area now, so that's a positive.
I actually go in tomorrow for my double mastectomy, and I've come to terms with it. Also decided to just go flat and use padded bras if I want to occasionally.
When I go tomorrow I'll be taking button up P.J's and a shirt to go home in with buttons (easier to put on) easy pull on comfy pants and necessities like my reading kindle, phone, charges, stuff like that.
I know I'll only be in for one or 2 nights then home to recuperate, so I've been freezing a few meals I've cooked up so I don't have to bother with cooking for a while, so that's something you could think of doing.
What type of tumors do you have? do you know? I have "Lobular".
It's very hard at first to get your head around, such a shock isn't it, but I hope you can find some comfort here, everyone's been wonderful and helpful to me.
