Breast Implant Rejection

I have performed many silicone implant reconstructions over the years, and have never had anyone "reject" an implant. Thus, while I think the chances of this happening are very small, nearly anything is possible in medicine. As mentioned in one of the responses to the above questions, however, there are other issues that can develop over time with implants, such as capsular contracture formation or leaks, but most patients do well with implants.
