A breast lift or mastopexy is achieved lifting the breast and nipple to their proper position on the chest as well as removing excess skin that causes the breast to sag. Aging, pregnancy, and weight gain, or weight loss are common reasons lead to skin stretch and a sagging appearance. In most cases, breast tissue is not removed – creating a more youthful breast appearance without altering the volume of the breast itself. Depending on the amount of skin required to remove to achieve the optimal result, two different incision patterns are possible.
