PFAS ‘Forever Chemicals’ Are ASSOCIATED WITH Liver Cancer

WEDNESDAY, Aug. 10, 2022 (HealthDay News) — A chemical called perfluooctane sulfate (PFOS) has been from the most common kind of liver cancer, a fresh study indicates.

PFOS are employed in an array of consumer and industrial products, and so are known as forever chemicals since they breakdown very slowly and accumulate both in the surroundings and in human tissue.

Researchers at the University of Southern California’s Keck School of Medicine combed through human blood and tissue samples gathered within a large-scale study. Then they compared samples from 50 liver cancer patients with 50 other people who didnt develop cancer.

Researchers found various kinds polyfluoroalkyl substances (PFAS) — the household of chemicals to which PFOS belongs — in the blood examples of patients taken ahead of their liver cancer diagnosis.

The strongest link was between PFOS and liver cancer. People who have PFOS levels in the very best 10% were 4.5 times more prone to develop liver cancer than people that have the cheapest levels, researchers found.

In addition they found evidence that PFOS disrupts normal metabolic processes in the liver, causing more body fat to build up in the organ. Fatty liver disease may increase the threat of liver cancer, and is likely to affect 30% of U.S. adults by 2030.

Some manufacturers have eliminated the usage of PFOS along with other forms of PFOA, but as the chemicals are long-lasting, they could be within the blood greater than 98% of adults in the usa, researchers said.

This builds on the prevailing research, but takes it one step further, Jesse Goodrich, a postdoctoral scholar in the department of population and public health sciences at Keck, said in a university news release. Liver cancer is among the most serious endpoints in liver disease which may be the first study in humans showing that PFAS are connected with this disease.

The findings were published Aug. 8 in JHEP Reports .
