There have been about 200 cases of BIL-ALCL – in other words breast implant associated anaplastic.  A recent article linked the development of this lymphoma to chronic inflammation via bacterial infection.  It is believed that bacterial antigens trigger the development of this type of lymphoma.  Usually this type of lymphoma develops years after implantation of a textured implant and usually begins as a sudden unilateral swelling on only one side of the breast implant pockets.  Usually treatment is total capsulectomy.  Survival is excellent and approaches 100%.
