Over time, breasts can droop or sag due to thinning of the skin. This is also very common after pregnancy or weight loss. A breast lift, or mastopexy, lifts the breast and nipple back to their proper position. Some people refer to this surgery as a “boob job.” The surgery sometimes uses breast implants.  The breast implants can add volume to the upper aspect of the breast or simply to increase the cup size. Breast lifts are sometimes combined with tummy tucks– aka, a “mommy makeover.”
