As of April 5th 2019, as a precautionary measure, France has banned certain types of breast implants. The ban concerns macro-textured and polyurethane (PU) coated breast implants. These are breast implants with a rough surface. France made this decision because they see indications that breast implants with a rough surface present an increased risk of BIA-ALCL. The Dutch Health and Youth Care Inspectorate asked RIVM to assess the scientific substantiation of the French decision.
