Improves and enhances the contour of a woman's breast. It is most commonly used to correct volume loss after pregnancy and to increase breast size. Breast surgery can also be used to help balance breast size asymmetries and as a post surgical procedure following other breast reconstruction surgeries. Breast implants can be placed above or below the muscle. Placement of implants can be through the armpit (trans-axillary), the nipple (peri-areolar), the bellybutton (trans-umbilical), or under the breast crease (infra-mammary).
