A really great tool to aid a plastic surgeon in breast reconstruction is the use of a patient’s own fat to reconstruct their mastectomy site. Especially if the site has received radiation. One concern brought up early in the discussion was whether or not the transplanted fat cells would encourage migration and metastasis of the breast cancer. A study in a breast cancer model studied this effect. They found that the transplantation of fatty tissue into the mastectomy site DID NOT increase the risk of metastasis. This is great news because more and more I utilize a patient’s own fat to help reconstruct the mastectomy site.
