The problem is that not all the fat you inject survives, so probably 50-70 percent of the fat that you put in picks up a blood supply and becomes permanent fat within your breast, and then that is permanent. The remaining 30-50 percent will often dissolve away, so it can be a little disappointing in one operation, that you get a lovely, pumped up breast, it gets swollen, the patients are delighted, they think it looks great, and over the course of six weeks it goes down a little bit. So it’s usually an operation that requires two procedures, and sometimes a third procedure, to get adequate volume. You don’t get the same volume as you would with an implant, in one go, but you can match that volume with two or three procedures.
