Breast augmentation can also be performed by transferring fat cells into the breasts from other areas of the body. The fat cells are harvested using liposuction. The extracted fat is then separated and concentrated from surrounding fluids. After processing, the fat cells are injected into the breast tissue. This is meticulously done in a layered fashion in order to maximize the viability of the transferred fat. As with any fat transfer procedure, not all of the fat will survive.
Fat transfer breast augmentation is most effectively used for small increases in breast volume. The procedure is used for breast asymmetry, to improve breast implant related issues such as visible rippling and to improve results of breast reconstruction after breast cancer surgery. Given the current technology, fat grafting only offers limited volume enhancement when compared to breast implants.
