When considering fat grafting as an option for breast enhancement, it is essential to understand the principles of the procedure, as well as the benefits and risks involved. Breast lipofilling involves removing fat from an unwanted area of the body and transferring it to the breasts. The fat is removed by liposuction, filtered, and injected as a graft into your breasts. The surviving grafted fat lives a normal life cycle similar to natural breast fat. When the procedure is successful, the benefits are soft natural breasts without any foreign material.  Unfortunately, breast enhancement by using fat grafts is inconsistent. Typically, 30-40% of the grafted fat does not survive the journey. This limits the magnitude of volume enhancement. Additional drawbacks to breast lipofilling include the risk of breast irregularities and cysts resulting from non-surviving grafts of fat.
