First Oncology appointment - what to expect/ask?

I got told if I had to have radiotherapy it would be a year before I could have reconstruction but since it’s just chemo I could go ahead at any time. I’m going to go to a breast reconstruction evening if it fits in with work to get the lay of the land and find out what is involved and out of pocket costs. If I was in my 20’s or 30’s I would do it for sure but I’m not too worried about it apart from my lack of symmetry - probably if I would end up with really bad scarring that would prevent me for wearing even more clothes I might not do it.
