For women who decide not to have a double mastectomy, with only the one breast removed (unilateral mastectomy), it may be important to alter the unaffected breast to match the newly reconstructed breast. Options to match the healthy breast to the reconstructed breast include a breast lift (mastopexy), breast reduction, or adding an implant (breast augmentation). These symmetry (matching) procedures on the healthy breast are covered by insurance. Alternatively, if a woman chooses to have a double or bilateral mastectomy, reconstruction surgery is then performed on both breasts. Insurance also covers the reconstructive surgery of both breasts.
