In 2011, when the U.S. Food and Drug Administration first warned of a linkย between breast implants and a mysterious new cancer, it said the risk was vanishingly rare, far less than one in 500,000.

Now, seven years later, the scientific consensus is that implants with textured surfaces โ€“ not ones with smooth surfaces โ€“ cause the disease, called breast implant-associated anaplastic large-cell lymphoma. And although it certainly isnโ€™t common, it is far less rare than originally believed.
