Background
Over the last 30 years there has been interest in the use of autologous fat transplantation for breast reconstructive and cosmetic purposes. Up until now injection of adipose tissue into the breast has been subject to two limiting factors. First, fat injection into the breast could result in fat necrosis, cyst formation, and indurations that could be mistaken as cancerous calcifications. Second, the degree of reabsorption of the injected adipose tissue is unpredictable.
