But for your info...
I had bilateral mastectomies with immediate expanders implanted. Unfortunately, my hospital sent me home with a pseudomonas infection that almost killed me. So, I lost the expanders and chose not to try again.
Most of my chest is still numb, 3 years later, as are my armpits.
Maybe someone who has had diep reconstruction will answer you.
My sister had bilateral tram flaps with many complications.
My decision to have bilaterals started out as prophylactic too, since I have a very strong family history and the BRCA2 mutation and an area of microcalcifications that was suspicious.
I had good insurance, DID NOT LET THEM KNOW I HAVE THE BRCA2 MUTATION, since the law does not protect us yet! My surgeon got the approval based on family history. I was once rejected for insurance coverage by Kaiser because of my family history...So you all need to keep this kind of info in check.
Good luck, good life...fight this horrible disease with everything you've got. I believe you are on the right path with prophylactic, I have had 6 family members and myself have this disease...2 of us are still alive.
