PTFE (polytetrafluoroethylene) is Teflon(TM), which people will tell you causes cancer or whatever. It might. If you ever get exposed to it.
People scream about "Risk!" without comprehending what it really means, even qualitatively.
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:
