There are often times when patients may undergo a lumpectomy with an oncoplastic reconstruction of the lumpectomy defect and then in the future undergo a mastectomy. This may happen in patients who have a genetic mutation that puts them at higher risk for breast cancer. In these patients, the nipple areola complex may be preserved as it is re-positioned to a higher location on the breast. The nipple areola complex blood supply is then re-established and a mastectomy can be performed with a higher chance of remaining viable after the mastectomy. In these patients hyperbaric oxygen therapy is a helpful adjunct to facilitate wound healing and maintain nipple areola complex blood supply.
