Please let me know if you find out the answer to your question. I have two more chemo treatments and then I will be facing the same issue. I found the expanders to be the worst part of this whole ordeal. I would hate hate hate..to finally get my implants and have the radiation ruin them. I have been trying to find out if I can put off the surgery until after the radiation. However, if you still feel the effects of the radiation 9 months later ??? I could never wait that long !!
