Both my Medical oncologist and my Radiation oncologist told me that having the re-excision and then the radiation would give me the best chance for it not to return. Your DCIS seems similar to mine and if you have positive margins I would think your best bet would be to have the surgery and pray they get it all and then do the radiation. But you have to do what you feel is best for you. I will be praying for you!
