NEW YORK (Reuters Health) - Worried about what to do with fat you've had liposuctioned from pudgy areas? Researchers have turned it into stem cells in the lab, but here's a more immediate use: Fat liposuctioned from other parts of the body can safely be used to increase a woman's breast size, according to study findings presented this week at the Plastic Surgery 2009 meeting in Seattle.
Many surgeons are already "using liposuctioned fat to reconstruct breasts after mastectomy," Dr. Luis Zapiach, a plastic surgeon in Hackensack, New Jersey not affiliated with the study, told Reuters Health.However, injecting fat into the "breast for cosmetic purposes has been a controversial issue ever since the American Society of Plastic Surgeons banned the procedure in 1987," Dr. Roger K. Khouri, a plastic surgeon in Key Biscayne, Florida, who performed the current study, told Reuters Health.
"The procedure had the reputation of being ineffective, unreliable and potentially dangerous," Khouri said, and at present is not permitted outside of clinical studies.
With reconstructions following breast cancer surgery, Zapiach explained, all of the breast tissue is removed before the fat is injected, so there is no danger that fat - which excretes estrogen, a hormone that stimulates breast cell growth - will bring the cancer back.
With cosmetic augmentations, the tissue still remains, so "there is a theoretical risk that use of fat for augmentations could increase the risk of breast cancer," Zapiach said.
In the current study, however, which was small, there was no evidence to support concerns that the transferred fat may increase the risk of breast cancer.
The current study featured 50 women who had their liposuctioned fat used for breast augmentation. X-rays were used to look for dead tissue and breast cancer 3 to 12 months after the operation.
A key component of the operation, according to Khouri, was the use of a bra-like device he invented called the Brava. The device includes a small battery-operated pump that creates suction on the breast. That, in turn, increases volume and promotes the growth of blood vessels in the area. The device was worn for 4 weeks before the operation and for a few weeks afterward.
