I think the Teflon question is different though. It is like lead in a sense, we know it is carcinogenic, just like we know lead is a neuro-poison. The only question is whether we are doing good enough job at preventing it from leaking into our bodies.

With lead, a lot of people thought so, but still they put it in our gasoline, in solder for our water pipes, etc. and a lot of people got some pretty bad neuro-developmental disorders as a result. I certainly hope we are not repeating the same story with teflon, though I, personally am not willing to risk my and my families bodies to it.
