Question: I recently had a mammogram, and while discussing my implants with the technician she informed me that they have an expiration date. Is this true? Will my implants "expire"?Answer:Good question. The truth is that all implants have an expiration date, including hip or knee replacements, and breast implants. The innumerable factors for replacement are determined by the integrity of the implant and by the patient, so it is impossible to tell if or when they will need replaced - if ever. The best protocol to follow when getting breast implants is to partner with a surgeon who will be around for years to come, who can provide you with long term care in case you have any issues. I hope this helps.
