British researchers have concluded that PIP breast implants made with unauthorized silicone filler have twice the rupture rate of other types of implants, but they are neither toxic nor carcinogenic. Women have faced an “incredibly worrying time,” said National Health Service Medical Director Bruce Keogh, but his study found no long-term health threats for women with PIP implants. Approximately 47,000 women in the U.K. received the silicone implants, which were never approved for use in the United States. BBC (6/18)
