Fat grafting, also known as fat transfer, is a technique where fat is obtained by liposuction and processed to remove and isolate healthy fat cells. This fat is then injected to add permanent volume to areas of deficiency. It has the advantage of using a person’s own natural fat to permanently correct volume deficiency. This is used to enhance a breast augmentation or to correct volume lost by breast cancer treatment. As a standalone treatment, fat grafting may enhance breast volume. It can create a very natural appearance in the right patient but is typically not enough to create the same appearance as a breast implant.
