Synthetic “forever chemical” linked to liver cancer
Keck School of Medicine of USC researchers find that a common man-made polyfluoroalkyl substance (PFAS) may elevate risk of liver cancer.
Exposure to a synthetic chemical found widely in the environment is linked to non-viral hepatocellular carcinoma, the most common type of liver cancer, according to a new study conducted by researchers from the Keck School of Medicine of USC and published in JHEP Reports.
The chemical, called perfluooctane sulfate or PFOS, is one of a class of man-made chemicals called per- and polyfluoroalkyl substances, or PFAS. These chemicals, which are used in a wide range of consumer and industrial products, are sometimes called forever chemicals because they break down very slowly and accumulate in the environment and human tissue, including the liver.
