--this is not an issue limited to breast implants--or even to cosmetic implants, which are a large fraction of, but not all of (as Dahlek notes) breast implants.

There are a number of people with reconstructed knees who have had similar symptoms/troubles. I don't know as much about people who have had (cosmetic and non-cosmetic) nose work done, but I imagine someone can enlighten me.

From what I've seen so far, if the issue is purely aesthetic/self-esteem, the burden of proof would not rise to the level of getting implants done--too many risks. If it's done for reconstructive or other biomechanical reasons, the decision to go or no would come from a more nuanced calculation.
