After the ruckus with the DuPont lawsuit, major companies switched from PFOA to other PFC's, which still have to be dumped 'somewhere'. There is even less data on what these other assorted PFC's do to you.
On the nonstick pans, most are teflon. If you heat them up too much they release various polyfluorinated hydrocarbons:

The good news is that teflon pans release less than the TDI for humans (whatever that means - Total Death Induction? - I couldn't access the full article.).
The worrisome part about many PFCA's is that their half-lives in humans can be several years, so they could easily accumulate over time. They are water soluble and stable in the environment.
Alternatives to nonstick pans are ceramic and conditioned cast iron, and possibly silicone for baking. Alternatives to drinking water are more limited...
