It is likely that mastopexy will slightly reduce the size of your breasts, depending on which incision is used to perform the procedure. While there may be some slight reduction in order to tighten the skin on the breast, this reduction is typically not too significant. Many of my patients feel that their breasts are smaller with a breast lift because their breasts no longer have to be gathered and placed into undergarments, such as a bra. With mastopexy, the excess breast skin contributing to breast droop has been removed, creating a higher, tighter breast, which often gives the impression that the breast is smaller.
