Is it possible to harvest the fat from a relative with the same blood type to preform fat transfer breast augmentation?

And of course, blood type is only one of the markers needed to ensure any type of graft or organ transplant would be suitable (not to mention worthy of lifetime immunosuppressive therapy and the increased risk of lymphoma or other cancers). This is why organ, bone marrow, or other life-saving transplants are only done in the most exquisitely-matched (much more than blood type, most of the histocompatibility antigens must match or the graft/transplant will fail, and can even if they DO match) patients.As other have stated, identical twins could do this, but not mother and daughter, since half of your cellular material comes from your father. Not a match. Furthermore, the risks and medical difficulties with immunosuppressive drug therapy are not appropriate for elective cosmetic surgery. Kidney transplant to save a life and prevent dialysis; heart transplant to save a life, etc.--Sure, but not for breast augmentation when a superior alternative exists--breast implants.Sorry, but implants remain the best and safest choice of all.

The fat would be rejected from everyone except an identical twin.  Unfortunately, other members of your family are not close enough genetically for fat transfers from them to work for you.

   Only an identical twin could help with providing fat.  If you are thin, implants are still the most reliable form of breast augmentation.Kenneth Hughes, MDLos Angeles, CA
