It's not a good situation, because in the breast augmentation population it's often young women who are quite mobile, who might have the surgery done in one city and move to a different city for a job, or for family, or what have you. Even though they might have best intentions for follow-up and the surgeon may offer them follow-up, for one reason or another they have no follow-up.
Medical records are like tax returns. You have about a seven-year window in which you're supposed to maintain medical records, whereas with an implant, possibly, it's a forever rule. This is because, as Dr. Tervaert said, a lot of these conditions related to the implant seem to be latent effects, so that they might be 10, 20 or 30 years later.
