Hi @Invisjet,
Welcome to the forum lovely. Sux to be here for sure but you wont find a better bunch to walk you through the shitfight that is bc. It's a hard choice for you obviously. Ultimately there really is no right or wrong answer, you just have to go with your instincts.
Personally I had no problems deciding to keep the girls unless it was absolutely unequivocably the only option. So lumpectomy, chemo, rads and no regrets. Even though I do keep getting dodgy scan results.
I think we are all left with that "what if it comes back" no matter which option you chose. There are no guarantees either way unfortunately.
You could always do the rads and see how you feel. You still have the other option up your sleeve for later if you so wish. I believe the surgery your looking at is a big one. @Kmakm can probably shed some light on that one and I am sure there are many others as well.
Definitely have a chat with your BCN if you have one.
All the best with your decision sweet.
