Once breast implants are placed, they can have a very long life — although there is no way to specifically determine exactly how long each implant will last. As with any surgery, there are risks and complications. These can include scar tissue or ruptures that make it necessary to remove the implant. If an implant is made of saline and a rupture occurs, the body simply absorbs the solution. If an implant is silicone and ruptures, an MRI is required to determine if the condition is, in fact, a rupture. If the implant has indeed ruptured, it will most likely be removed and simultaneously replaced with a new one.
