If it's not leaking, leave it alone

Most plastic surgeons believe that if an older breast implant is not causing a specific problem or is not known to be leaking, it should be left alone. If you are happy with the breast appearance the implants are likely perfectly good. You need to have your routine mammograms that you have hopefully been getting. Unfortunately these xrays often do not show leaking silicone implants. An MRI could show leaking implants not seen on mammogram. If you are having any issue at all with change in size, shape, feeling of the breast I would get an MRI to check on the implant. Board certified plastic surgeons in your area should be able to guide you through this process.
