Here Are The Ways That PFAS Chemicals Might Cause Cancer, A New Study Says

From Greenland to West Virginia, cancer cases have been linked to exposure to the group of chemicals known as PFAS.

Now, a new study is going one step further to try to explain how some of these PFAS compounds, a family of thousands of synthetic chemicals that have been used for decades in everything from food packaging to nonstick cookware, might cause cancer on a molecular level.

PFAS, short for “per- and polyfluoroalkyl substances,” are known for building up in the body and persisting in the environment, giving them the nickname “forever chemicals.” They’ve caused widespread alarm after turning up in the drinking water of dozens of cities in the US, in some food items, in soil, and in people: In 2015, the National Health and Nutrition Examination Survey found PFAS in the blood of 97% of Americans. Last week, the EPA disclosed it “has multiple criminal investigations underway concerning PFAS-related pollution.”
