Mastopexy, also known as a breast lift, is a cosmetic surgical procedure that improves the shape and appearance of the breasts. A key factor in determining candidacy for a breast lift is ptosis, which refers to a dropping of the nipple and breast tissue below the inframammary fold (the crease beneath the breast). If you have sufficient breast volume and are bothered by sagging, a breast lift can help achieve a perkier, more youthful look. Breast lift surgery can sometimes be combined with breast augmentation (to increase volume) or reduction (to decrease size).It’s generally recommended to wait until after completing childbearing to undergo a breast lift, as pregnancy can again alter breast tissue.
