Aggressive cancer type linked to common chemical exposure in new study
New York Post • • health
Key Points:
- NIH research links higher blood levels of two PFAS chemicals, PFOA and PFOS, to an increased risk of aggressive estrogen receptor-negative (ER-negative) breast cancer, based on data from the Sister Study involving women with familial breast cancer risk.
- Women in the highest exposure groups had a 67% (PFOA) and 93% (PFOS) higher rate of ER-negative breast cancer compared to those with the lowest exposure, though no clear association was found with breast cancer overall.
- The study highlights concerns about legacy PFAS chemicals but notes limited knowledge about newer, shorter-chain PFAS replacements and their health impacts, emphasizing that findings show association, not causation.
- Experts recommend reducing PFAS exposure by avoiding contaminated drinking water, nonstick cookware, plastic containers, and certain personal care products, suggesting alternatives like stainless steel cookware and minimizing heating food in plastics.
- Health officials and researchers call for further investigation into environmental chemical risks to women's health, with the goal of providing clearer guidance and prevention strategies against aggressive breast cancer types linked to PFAS.
