Nationwide Peru Study Links Pesticide Mix to 150% Jump in Cancer Risk
A Peru-wide study links exposure to 31 pesticides with about a 150% higher cancer risk in high-exposure areas, using six-year environmental dispersion models and national cancer registry data (2007–2020). Indigenous and rural communities face greater exposure, averaging 12 pesticides. Early molecular analyses suggest pesticides disrupt liver function and cellular identity long before cancer develops, indicating non-genetic pathways to cancer and challenging traditional single-chemical risk assessments. None of the chemicals are currently WHO-classified as known human carcinogens. The findings call for considering real-world chemical mixtures and environmental factors like climate shifts in prevention and policy.
