Unfortunately, not all breast implants last forever. They typically come with a warranty, but may have to be replaced beyond the terms of the warranty, once the warranty expires. With that said, replacement typically does not have to take place unless there is a problem with the implant, such as rupture or capsular contracture (internal scar tissue). In such cases, procedures like breast implant revision are available. Many women have their breast implants for 5, 7, 10 years or more with no problems! In fact, many replacements are due to a desire for a change in size, not because of the age of the implants.
