Fat grafting, also called autologous fat transfer, is emerging as a new breast reconstruction technique. In fat grafting, fat tissue is removed from other parts of your body – usually your thighs, belly, and buttocks — by liposuction. The tissue is then processed into liquid and injected into the breast area to recreate the breast.
Another form of fat grafting, called lipofilling, has been used for a number of years to fix minor differences in the shape, balance, or position of the reconstructed breast compared to the other breast. Since that has worked well, doctors thought they might be able to rebuild a whole breast using fat.
