It concerns millions of people who use tap water.

A striking study has been published about "eternal chemicals" called PFAS, which have been used for decades in products ranging from nonstick coatings to firefighting foams because of their water, oil, and heat-resistant properties. Because these chemicals don't break down easily, they accumulate in soil, water, and living organisms.

An increase in cancer types was observed

Experts found an increase in digestive system, thyroid, respiratory tract, and some head and neck cancers in areas where PFAS was detected. Kidney and bladder cancers, as well as leukemia, were the most prominent in men, while the most significant increases in women were seen in thyroid and oral cavity cancers.

HOW WAS IT DETECTED?

The study compared district-level cancer data with PFAS measurements from public water systems. Other risk factors, such as smoking, obesity, income disparities, and air pollution, were also considered. The findings revealed a strong association between PFAS and different types of cancer.

BE CAREFUL ABOUT THE EFFECTS OF PFAS

Some types of PFAS are known to disrupt hormone signaling, burden the liver, increase chronic inflammation, and alter gene function. These effects further strengthen the link between the chemicals and cancer.

WHAT ARE THE WAYS OF PROTECTION?

Experts say the new legal limits for PFAS in public water systems may be tightened further. They emphasized that activated carbon or reverse osmosis filters can be used at home, and that regular replacement is crucial. Those using their own wells are advised to have their water tested by certified laboratories.

While the study doesn't offer definitive evidence on an individual basis, it highlights a direct link between PFAS concentrations in public drinking water and increased cancer cases. Experts say stricter controls, new treatment technologies, and long-term monitoring are crucial to ensuring public access to safe water.
