A Common 'Forever Chemical' Has Just Been Linked to Liver Cancer in Humans - ScienceAlert

A common 'forever chemical' known as PFOS (perfluorooctanesulfonic acid) has been linked to liver cancer in humans in a worrying new study.

Now a study by researchers from the University of Southern California and the Icahn School of Medicine at Mount Sinai in the US have confirmed an association between PFOS and the development of a particularly deadly form of liver cancer.

"When you are looking at an environmental exposure, you need samples from well before a diagnosis because it takes time for cancer to develop.".

Measuring levels of various types of PFAS in blood samples taken prior to the development of liver cancer, the researchers identified a strong association between PFOS and HCC.

Knowing where we can draw the line on a safe level of exposure will go a long way to refining regulations and supporting measures on monitoring environmental levels, without resorting to panic or risking the spread of misinformation.
