This will really set feminists off

Not that I thought very much of the concerns about the earlier versions of breast implants, but what objection can they come up with now?

British women may be offered a “natural” form of breast enlargement that uses stem cells and fat from a woman's own body, under plans being considered by doctors.

The technique, pioneered in Japan, results in breasts that look and feel smoother than conventional cosmetic surgery using implants. This is because the stem cells enable the fat to grow its own blood supply, thus becoming an integral part of the breast rather than a foreign lump.

Stem cells have the potential to change into any cells in the body. They are found in most tissues, especially fat. . . . .

Ironically, the procedure seems to have been originally developed in the US and will soon be forthcoming in the journal Tissue Engineering, but seems to be spreading around the world much faster than it is here. Presumably it is due to the regulatory environment in the US. The procedure using a woman's own fat cells seems to be even safer, but these regulatory delays will keep on having women use the artificial implants.
