DIEP- one surgery or two

Frogdog12

Hello! I am trying schedule a DIEP flap surgery and am torn between two PSs who both seem great. The only real difference is that one says he can do the procedure at the time of the mastectomy no problem and has better results that way. The other says no and she must wait for the final pathology report from mastectomy. I am DCIS grade 3 as of now and am opting for BMX. She does not want to have reconstruction if I may need radiation. The first doc who will do it once (and my oncologist) say that radiation is unlikely because of the BMX and would happen only if there is a lymph node problem. I really only want one surgery and recovery period because I have lots of little kids at home. Any advice?
