Exposure to Per- and Polyfluoroalkyl Substances and Liver Cancer: A Systematic Review of Animal and Epidemiological Studies

The global incidence and mortality rates of liver cancer are rising, necessitating research into environmental and lifestyle risk factors. Early onset liver cancer, diagnosed before the age of 50, is becoming prevalent, suggesting the potential influence of emerging environmental exposures. Per- and polyfluoroalkyl substances (PFAS) are ubiquitous environmental contaminants that have been linked to liver toxicity in humans and shown to cause hepatotoxic effects in animals, but their role in liver cancer remains unclear. This systematic review synthesizes evidence from animal and epidemiological studies to evaluate associations between PFAS exposure and liver cancer risk. PubMed and Embase were searched through…
