Breast implants are not considered lifetime devices, and over time they can wear out, rupture, or leak. The FDA recommends that women with breast implants undergo routine imaging exams to check for implant ruptures or leaks, and they should have their implants removed and replaced if necessary. However, leaving breast implants in longer than 10 years does not necessarily mean that they will cause harm, and many women choose to keep their implants for longer periods without experiencing problems.
