PFAS chemicals linked to thyroid cancer, human data suggests
By Shannon Kelleher
Exposure to some per- and polyfluoroalkyl substances (PFAS) may increase thyroid cancer risk, according to a study published Tuesday. The analysis, which compared blood samples from 88 people who developed thyroid cancer with samples from people who did not, is the first to document an association between PFAS and thyroid cancer, which had been previously hypothesized.
