I was first diagnosed in 2003 with DCIS and had a double mastectomy ( my choice) followed by a Tram flap reconstruction and my oncologist said That I didn’t need chemo or radiation and was released. Exactly 20 years after my first cancer I went to Dr after having pain in my left breast and was diagnosed with cancer again. They did a study and it wasn’t the same cancer reoccurrence, they believe it was in the skin flap from my abdominal muscle they used for reconstruction and excess estrogen caused second cancer.
