Breast implants are not designed to last indefinitely in the human body. There are certain indicators that your breast implants may need to be replaced sooner rather than later. These include hardening of the breasts, hard nodules or lumps on the breasts, a change in breast shape, pain, or noticeable signs of leakage. After your breast augmentation procedure, it is important that you receive regular mammograms or other imaging screenings. These can help you spot leaks or other changes in breast tissue well before prominent symptoms occur. Also, stay in communication with your plastic surgeon. If you've had the same breast implants for a decade or longer, it is wise to discuss the potential complications that may arise, how to spot them, and also how to avoid them.
