Oncologists Urge Discarding Damaged Non-Stick Pans Due to Chemical Risks

Oncologists are increasingly advising people to discard old or damaged non-stick pans, citing potential health risks associated with chemicals used in their coatings. While studies do not directly link these pans to cancer, the chemicals involved raise significant concerns.

Dr. Mark Ashamalla, head of radiation oncology, emphasizes that owning such a pan doesn't guarantee a cancer diagnosis but suggests avoiding them is a prudent step to reduce risk. Dr. Avishek Kumar advises making small, smart substitutions, noting that cancer risk is cumulative, influenced by genetics, lifestyle, and decades of minor exposures.

If you want to reduce your odds of cancer, avoiding it is a smart step.

The primary concern with older pans, especially those made before 2015, is PFOA (perfluorooctanoic acid). This chemical, part of the PFAS group, has been associated with an elevated risk of kidney and testicular cancer and is classified as carcinogenic to humans. Even newer "PFOA-free" cookware may use substitute chemicals like GenX with similar toxic profiles.

Modern non-stick pans often use PTFE (Teflon), which is generally safe but becomes risky when overheated above 260 degrees Celsius. Overheating can cause the coating to break down, releasing toxic fumes that mimic flu-like symptoms, a condition known as "polymer fume fever." It is crucial never to heat an empty non-stick pan.

Physical damage to the coating presents an even greater risk. Scratched, worn, or peeling pans can release millions of microplastic and nanoplastic particles into food. A single crack can release thousands of particles, while a deeply damaged pan can release millions. When the coating is compromised, the pan actively contaminates meals with harmful substances, making it a candidate for immediate replacement.

When the coating is damaged, you are exposed to substances in a way the manufacturer never intended.
