A study analyzing over 40,000 cases and controls suggests potential associations between prenatal exposure to per- and polyfluoroalkyl substances (PFAS) in drinking water and an increased risk of certain childhood cancers. Researchers examined data from 10,220 children diagnosed with cancer in California from 2000 to 2015 and found suggestive associations between PFAS exposure and various childhood cancers.

The study notes that prior epidemiologic studies on PFAS and childhood cancer risk have been limited and recommends future research to incorporate direct maternal serum measurements and broader population studies.
