A new study funded by the National Institutes of Health has found that women with elevated levels of two common per- and polyfluoroalkyl substances, or PFAS, face up to a 93 percent higher rate of an aggressive form of breast cancer. The research, published this week, examined exposure to the persistent chemicals, often called “forever chemicals” because they do not break down in the environment or the human body, and their association with rapidly progressing tumors. Scientists say the findings add to a growing body of evidence linking PFAS to serious health risks and warrant closer scrutiny of widespread exposure.
PFAS compounds are used in thousands of everyday products, including nonstick cookware, water-repellent clothing, food packaging and firefighting foam, and contaminate drinking water supplies across the country. Researchers cautioned that the study identifies an association rather than a direct cause, and further work is needed to confirm the biological mechanisms involved. Public health advocates said the results strengthen calls for stricter regulation of the chemicals, while federal agencies continue to assess exposure limits. The study authors urged additional research into how these substances may influence cancer progression, particularly among women at elevated risk.
