Because breast implant surgery is more often performed using general anesthesia, it is associated with the same risks as other invasive surgical procedures. After breast implant surgery, patients might experience swelling, hardness, discomfort, itching, bruising, twinges and pain over the first few weeks. Potential adverse events that may occur with silicone gel-filled breast implant surgery include capsular contracture, rupture, changes in nipple and breast sensation, infection, hematoma/seroma, delayed wound healing, implant extrusion, necrosis, granuloma, breast tissue atrophy/chest wall deformity, lymphadenopathy, gel diffusion, gel fracture, breast implant associated anaplastic large cell lymphoma (BIA-ALCL) and others. Talk to your doctor about other complications.
