PTFE (polytetrafluoroethylene) is Teflon(TM), which people will tell you causes cancer or whatever. It might. If you ever get exposed to it.

Risk = exposure * hazard. therefore .... No exposure = no risk.
regarding your Teflon coated cookware which you threw out after being told that it would give you cancer:
