Women exposed to several widely used chemicals appear to face increased odds for ovarian and other certain types of cancers, including a doubling of odds for melanoma, according to new research funded by the US government.

Using data collected by the Centers for Disease Control and Prevention (CDC), a team of academic researchers found evidence that women diagnosed with some “hormonally driven” cancers had exposures to certain per- and polyfluoroalkyl substances (PFAS), which are used in thousands of household and industrial products, including in stain- and heat-resistant items.
