Hi and welcome to the club that no body wants to join! I don't have any guidance on the reconstruction/prosthetic stuff as I opted to have a lumpectomy instead. I was stage 1 with no node involvement. Like you, I was young, 37 with no family history. I tested negative for the gene. I also have two daughters who are now 10 and 8. Just wanted to wish you the best along your journey. It DOES get easier and there IS life after diagnosis. Hang in there and let us know if we can help. Hugs!
