I had 2 excisions, chemotherapy, and, because of unclear margins, ended up with a mastectomy and immediate tram flap
reconstruction. Three years out, I look and feel great.
My friend had DCIS only, and went for many opinions (surgeon, breast specialists, and two different oncologists). Within 2 weeks of diagnosis, she had a mastectomy, which all had recommended, and immediate DIEP flap reconstruction.
