Mastectomy Question

It depends. Usually there is enough skin remaining to cover the wounds. With skin-sparing mastectomy, there is more than enough skin remaining. If the skin covering the breast/s seems diseased (or likely diseased) with breast cancer, though, more of it is excised.

Understand, for purposes of this discussion, the skin covering the (intact) breast/s is to be distinguished from the breast/s (or breast tissue). There is usually an elliptical incision done, and the skin within that elliptical area is taken along with the breast tissue from within. It is not as if the (intact) breast is shaved (or sheared) off.

For persons having autologous tissue reconstruction with skin flap/s transferred from elsewhere, the skin covering of their reconstructed breast/s comes from their donor site/s.
