Breast augmentation (breast enlargement, augmentation mammaplasty) is a surgical procedure that can add volume or restore fullness of the breast by placing breast implants. In the US, over 300.000 women undergo the procedure every year. It is the most common elective cosmetic surgery performed today in the US.
Breast lift is a procedure done to raise and firm saggy breasts. The sagginess may result from pregnancy, breastfeeding, weight fluctuation, aging, and hereditary factors. During the procedure, excessive skin is removed and the breast is reshaped to create more youthful appearance. Enlarged areolae may be reduced.
Breast reduction (reduction mammoplasty) is a surgical procedure performed to treat symptoms related to excessively large breasts, i.e. back pain, neck pain, shoulder pain, rashes in the folds under the breasts, and shoulder grooving (from bra straps). The procedure involves removing part of the breast to reduce volume, then repositioning the nipple/areola to a higher location (lift).
True gynecomastia (enlarged male breast) is a condition resulting from imbalance between testosterone and estrogen production. Although many people think that estrogen is a female hormone, men also produce it (although in much smaller quantities). Since estrogen is a hormone controlling the growth of breast (among other roles), its overproduction or imbalance with testosterone (male hormone) may result in enlarged breast gland in males.
