Jane Hoppin, Project 1, was part of the panel that reviewed PFOA and PFOS for carcinogenicity. As a result, PFOA was classified as a Group 1 carcinogen (Human carcinogen) based on sufficient bioassay evidence and strong mechanistic evidence (epigenetics and immune impacts). The Human cancer evidence was regarded as limited, but some evidence for kidney and testicular cancer.
And, PFOS was classified as Group 2b (possible human carcinogen) based on limited bioassay evidence and strong mechanistic evidence. Human cancer evidence for PFOS was limited. Click HERE to read more.
