Regardless of if you choose saline or silicone, no breast implant should be considered a lifetime medical device. This means that it’s likely you’ll need to have your implants replaced at some point down the line.
Although women with saline implants can easily see if one of their implants is leaking, to assess the integrity of silicone implants and make sure they aren’t leaking, the FDA recommends MRI screenings every two years beginning three years after surgery.
Aside from leakage, body variations brought on by weight changes or pregnancy make change the way your implants look, and if you do not like the resulting appearance, you may want to switch to a different size or material.
