At the FDA meeting the decision was clear that leaking implants should be removed as soon as possible, and that almost always it isn't obvious that an implant is leaking. That's why the MRIs are so important. I guess that's one difference between the Health Canada panel and the FDA panel. They felt very strongly that once it starts leaking...well, even if it's broken, it's going to start leaking and it should be removed right away.
