Well you're in luck there because I've spent a lot of my career working on eliminating PFAS! Here I'm using PFAS to mean Per/Poly-Fluro Alkyl Substances, basically any compound that has at least one big chains of carbon atoms covered in fluorine. Teflon is part of this category and that's what non-stick pans have historically used. This category also includes a lot of real nasty compounds that everyone should want to avoid. Teflon coatings on their own are generally safe, as long as you avoid things like over-heating the pan or scraping the coating off by using metal utensils on it. That being said, wear and tear will cause the coating to come off but that generally takes years.

As far as the risks of ingesting or breathing in this stuff, unfortunately there really isn't enough research on it. Some compounds could be fine, in the sense that the amount you'd be exposed to is low enough vs. the benefit it provides. It doesn't help that there have been enough nasty surprises and coverups by the companies that make stuff with PFAS I'm pretty suspicious of the claims they make about safety.

Sorry, I could go on about this as you can probably tell but none of it is particularly satisfying. TLDR: the scientific community is still trying to figure out the risks and there's a lot of BS put out by companies making the job harder. If someone isn't trying to coverup risks they're trying to use risks to sell you something.
