The short answer
The American Cancer Society reports no proven cancer risk to people from using nonstick (Teflon) cookware. Older concern focused on a manufacturing chemical, PFOA, which has been phased out of nonstick coatings since around 2013. PFOA and related 'forever chemicals' are studied for possible links to some cancers, but that is about exposure sources beyond today's pans.

The full explanation.
The claim
Nonstick pans — often called by the brand name Teflon — are widely rumored to cause cancer, especially if scratched or overheated. The worry blends into broader concern about 'forever chemicals' in the environment.
What the evidence shows
The American Cancer Society states there are no proven risks to humans from using cookware coated with Teflon or other nonstick surfaces. The historical concern was not the finished coating but a chemical used to make it, called PFOA, which has been phased out of nonstick cookware in the U.S. since around 2013. Today's nonstick pans are made without PFOA.
The 'forever chemicals' question
PFOA belongs to a large family of long-lasting chemicals called PFAS. Some studies have linked PFOA to a higher risk of certain cancers, such as kidney and testicular cancer, and a cancer research agency has classified PFOA as carcinogenic based on that work. But this concerns exposure through sources like contaminated water or past industrial use — not the act of cooking on a modern nonstick pan.
The bottom line
Based on current evidence, using a nonstick pan is not a proven cancer risk. Sensible care still helps: avoid overheating empty pans (very high heat can release fumes) and replace badly scratched cookware. The larger 'forever chemicals' issue is a real area of study, but it is about broader exposure, not everyday nonstick cooking.

Common questions
▸Do nonstick pans cause cancer?
The American Cancer Society reports no proven cancer risk to people from using nonstick cookware.
▸What about PFOA and 'forever chemicals'?
PFOA has been phased out of nonstick coatings since around 2013. It is studied for possible cancer links, but that concerns broader exposure, not today's pans.
▸Is it bad to use a scratched pan?
It is not a proven cancer risk, but replacing badly scratched cookware and not overheating empty pans is sensible.
▸Can overheating a pan be harmful?
Very high heat on an empty nonstick pan can release fumes, so avoid overheating — this is separate from any cancer claim.
