How much fat is needed to increase bust size one cup with fat transfer, and is there much volume loss 6 months to a year after the surgery?
Outcome is not entirely predictable, but in general 1/2 of the fat injected will absorb away. I have found that fat grafting to the breast results in a nice enhancement with increased roundness and lift, but does not provide more than 1 cup size of augmentation. I recommend you contact a Board certified plastic surgeon in your area who performs breast augmentation with fat grafting to see if you are a good candidate and some representative results.
