PTFE? It’s so non-reactive that it is commonly used in medical implants, precisely because of its high biocompatibility. I don’t think that there are any connections at all between PTFE and cancer.
"While PTFE is stable and nontoxic at lower temperatures, it begins to deteriorate after the temperature of cookware reaches about 260 °C (500 °F), and decomposes above 350 °C (662 °F).[58] Over 400 °C (752 °F) pyrolysis occurs and more decomposition becomes significantly more rapid. The main decomposition products are tetrafluoroethylene (TFE) and difluorocarbene radicals (RCF2).[58] The degradation by-products can…
My oven goes up to 250 °C, though I never use it above 220. What cooking processes go to each of these thresholds?
