Breasts can also be enlarged by a persons own fat tissue that contains stem cells as well. It is important to emphasize that a certain amount of fat is needed for this operation and is most often taken from belly, hips, inner thighs or less frequently, the arms. Ideally, about 200 to 400 ml of fat is transplanted into each breast, increasing it 2-3 sizes. A portion of the fat will be absorbed by the body’s natural processes, and therefore the final result may differ with time from that post surgery. Fortunately, 50 to 70% of the transferred volume will remain. The procedure can be repeated multiple times in order to further increase or perfect the existing appearance.
