Radiotherapy or masectomy

I had clear margins and no lymph node involv. But before Radiation I asked myself the same questions. I went to my female surgeon and said Im worried it will come back in my beasts.  I said , you see this all the time, what would you do. Her answer was without hesitation and she said, mastectomy. She said I see it come back all too often.   I decided to also remove my healthy breast. Now recovering after immediate reconstruction.
