Although fat grafting to some parts of the body (like the face and buttocks) have proven to be very safe and successful, injecting fat into the breasts for cosmetic enhancement has many problems. This is why I prefer breast implants for augmentation.

The disadvantages of fat grafting breast augmentation are:

  • No large clinical studies with long-term follow-up have been done on fat grafting. We don’t know if this technique will work for all women and we also don’t know how long the results will last.
  • Depending on which surgeon you choose to do the procedure, you may be required to wear the Brava device or another type of external tissue expander for 4 or more weeks before the fat injections and for several weeks after.
  • The injected fat may be reabsorbed by the body and you may lose some breast volume over time, requiring repeat procedures.
  • Because some fat cells can stimulate cell growth, some doctors are concerned that fat injected into the breast area may cause dormant breast cancer cells to grow; research needs to be done to see if this concern is valid.
  • Breast cancer screening by mammogram is not possible after this procedure. Women must rely on MRI and frequent breast biopsies to screen/rule out breast cancer.
  • Some of the fat injected into the breast area may die, which is called “necrosis;” symptoms of necrosis may include pain and bleeding, the skin turning dark blue or black, numbness, fever, and sores that ooze a bad-smelling discharge or pus
