Platinum
Platinum is a chemical element with symbol Pt and atomic number 78. It is a dense, malleable, ductile, highly unreactive, precious, silverish-white transition metal. Its name is derived from the Spanish term "platino", meaning "little silver".
Breast implant
Platinum is a catalyst used in the making of silicone implant polymer shells and other silicone devices used in medicine. The literature indicates that small amounts of platinum leaches (leaks) from these implants and is present in the surrounding tissue. The FDA reviewed the available studies from the medical literature on platinum and breast implants in 2002 and concluded there was little evidence suggesting toxicity from platinum in implant patients. The FDA revisited this study and additional literature several years later, reaffirming prior conclusions that platinum catalysts used in implants is likely not ionized and therefore would not represent a risk to women.
