NotThamesWater-
the first non-stick was Teflon under the brand Tefal. Most ones you buy these days aren't specifically Teflon but very similar.
Edit - I read your question wrong. There's studies that say teflon and similar aren't carginogenic but if I remember right their independence was questionable and they focussed on heating the teflon to failure rather than real world use and how it acts when scratched and chipped. The basic outcome was they're fine until they start chipping and then you'll be ingesting loads of it and no one wants to be full of flourocarbons so chuck it.

My preference is anodised aluminium. It's not quite as non-stick as teflon but you can't scratch the coating off and isn't a carcinogen if you do.
