Researchers at the University of California found that fluoride surfactants (PFAS) found in the coating of nonstick pans increased the risk of liver cancer by more than 4 times. The scientists’ job was: published in JHEP Reports.
PFAS is a synthetic chemical that is highly resistant to oil, dirt and water. This makes PFAS indispensable for non-stick coating of pans, cosmetics, gels, lotions, toothbrushes, upholstery and more. At the same time, such substances decompose very slowly and accumulate in the environment and in human tissues, including the liver.
Previous animal studies have shown that exposure to PFAS increases the risk of liver cancer. The new study confirmed the link between liver cancer and PFAS in humans.
The team analyzed data from more than 200,000 people collected as part of a large epidemiological study on the development of cancer and other diseases. The researchers took 50 participants who had developed liver cancer and compared blood samples from people without cancer with blood samples taken before they were diagnosed.
The researchers found several types of PFAS in the blood samples of the first group. According to the scientists, the probability of developing liver cancer at high PFAS levels was 4.5 times higher than at low levels.
The researchers explained that PFAS alters the normal metabolism of glucose, bile acids, and amino acids in the liver. This leads to more fat accumulation in the liver and cancer.
