Plastic surgery to reduce the size of the breasts, also referred to as breast reduction surgery or reduction mammoplasty, is a procedure in which the breasts are resized and reshaped through the removal of tissue and skin. There are certain risks, complications and limitations of a breast reduction that should be considered before deciding to undergo plastic surgery.

Scarring
Immediately following surgery, the scars will be swollen and red. These scars may fade over time, although some women may have very noticeable scarring long after surgery.
Uneven breasts and/or nipples
Because tissue and skin are removed during a breast reduction, it is possible that the breasts will not be the same size and shape, or the nipples may not be evenly positioned. In some cases, where it is necessary to remove the areola and nipple and reattach in a different location, this risk may be increased. There is also a risk of partial or complete loss of the areola and nipple.
Diminished sensation
There may be a loss of feeling in the nipple, which could be permanent. If it was necessary to remove the areola and nipple, the loss of sensation will most likely be permanent because the nerves are severed during this process.
Inability to Breastfeed
Depending on the type of breast reduction performed, some women may have difficulty breastfeeding, and others may not be able to breastfeed at all.
Changes in the skin
Changes in the skin pigmentation and discoloration may occur and could be permanent.
Damage to the blood supply
Healing of the incisions may be delayed if damage to the breasts’ blood supply occurs during surgery.

Other more serious risks include reaction to the general anesthesia, infection, bleeding during the surgical procedure which could require blood transfusions, fat necrosis, and blood clots that could be life threatening. It all depends on the types of breast surgery that had been done for example breast implants or inverted nipples will heal quicker than a breast uplift or a breast reduction.
