 Platinum is a means used in the creating of silicone implant polymer shells. The literature points out that the platinum leaches (leaks) from these implants and is present in the surrounding tissue. In 2002 FDA evaluated the accessible studies from the medical literature on platinum and breast implants; however, the studies had estimated platinum in the implants, but not in the women's bodies.
In May 2006, researchers published a peer-reviewed study concluding that "women exposed to silicone breast implants have platinum levels that surpass that of the general population." This was the first report "to document the various platinium oxidation states present in samples from women exposed to silicone breast implants." This revision reported that platinum transfers from silicone implants by means of the lymphatic and blood systems and may accumulate; preserving years after the silicone gel breast implants have been removed. Patients with silicone breast implants had around 100 times higher platinum levels in their breast milk than women with no recognized platinum experience. Platinum levels were as much as 1,700 times higher in urine. On the other hand, more important than the levels of platinum was the oxidation state; the platinum in breast milk and other body liquids was ionized, first in the form of platinum salts, and therefore potentially toxic. The FDA reviewed the study, criticized the small sample, and noted that previous research reviewed by Brook, an Inamed consultant, has indicated that the platinum in implants is not ionized and therefore would "not represent a significant risk to women." According to the FDA website, the FDA has been asked to conduct additional research by researchers without financial ties to implant makers, to replicate or refute the study of ionized platinum in the bodily fluids of women with breast implants.
