Talking to my oncologist I asked him best surgery for my type of cancer. I also asked about reocurrence percentage for each procedure.
My tumor was large and near chest wall, he recommended masectomy, which I did. I am almost to my 5 year mark. I am grateful and glad I had the masectomy in my case. My cancer was a rare TNBC Lobular.
Ask alot of questions to help make your decision.
