A study by the University of Southern California found a link between exposure to 'forever chemicals' (PFAS) and liver cancer risk. The study analyzed blood samples from over 200,000 people and found that those with high levels of certain PFAS chemicals were more likely to develop liver cancer. The chemicals, commonly used in nonstick cookware and makeup, have been linked to various health problems. The study suggests that PFAS may interfere with normal liver function, leading to a buildup of fat and potentially nonalcoholic fatty liver disease.
