The study didn’t actually find anything related to cookware. Modern Teflon in the US doesn’t expose people to PFOA/PFOS like old version did due to new regulations. The chemicals could also be entering peoples body’s through drinking water or bioaccumulation in meat or plants.
You should throw away nonstick cookware from before 2013, but new nonstick cookware sold in the US does not have PFOA. I believe the EU followed suite recently.
Edit: After doing more research based on many comments here, I realized I was wrong. The brand Teflon replaced PFOA with GenX, a different fluorosurfactant that's probably worse than PFOA. From what I can tell, fluorosurfactants are more or less required to make PTFE and it seems quite likely that all fluorosurfactants are toxic. Personally I choose to use Teflon for eggs and stainless or cast iron for everything else. That feels like a decent trade off to me comparing years of life lost from liver cancer to time spent scraping scrambled eggs off of pans.
I want to add that a lot of cool startups are working on PFAS remediation. One I know of is Cyclopure, they make a Brita filter replacement that filters out PFAS (it's very expensive at the moment, though). Probably worth it if you live near a chemical plant, airport, or US military facility (airports and military bases both use PFAS fire-extinguishing foams which they typically fail to contain).
