Can you transfer fat from my sister's breasts to mine?

There has been a case presented of triplets; where one of the three quite slim triplets wanted breast enhancement. The other two were satisfied with their breast size. As each of the triplets was fairly slim there was not adequate fat for fat grafting for breast augmentation. However when liposuction and fat harvesting was done from all three identical triplets, there was adequate fat for one successful fat transfer breast augmentation.So yes it has been done, but so far only in identical siblings, and using only fat from regular body liposuction, and not by removing breast fat or breast tissue for the transfer.

You are unable to do a fat transfer from one person to another. Your body will reject the fat! Your sister should consider a breast reduction and you an implant.
