Autologous fat transfer, which involves using your own fat harvested via liposuction and transferring it to the recipient site in your body, has been used with good results in breast augmentation and reconstructive procedures. There is a limit to the amount of fat that can be injected at each setting, however. Therefore for breast reconstruction, it is usually used as an adjunct for touching up after the initial reconstruction.
There has also been a concern in patients who receive fat transfer to the breasts and breast cancer surveillance. Multiple studies have shown that a trained radiologist will be able to distinguish between a suspicious lesion and transferred fat on a mammogram or ultrasound, therefore there is no need to be worried.
