It's possible for you to move excess fat from your thighs and tummy, up to your chest. This especially helps women who are done with breastfeeding and their breasts shrunk to smaller than original size and they have imbalanced / out of shape breasts on each side. You're using your own body fat from one part of your body and moving it to your chest.
The fats are cleaned first (through centrifuge and all) before it goes into your targeted location.
Some of the fat cells may die off, but not all of it.
As for me, I just personally want to shift my excess fat from thighs (saddle bags and inner thigh) and tummy, up to the chest. Because why not? It means I can have slimmer legs and tummy, and move it up to have bigger chest.
Yes, a friend of mine did this with Dr Leo Kah Woon at Mount E. Breast enhancement through fat transfer. It involved doing liposuction first and the fat obtained is transferred to the breast. It's a good alternative if you don't want to get implants.
