A major study published in *Nature Health* indicates that living in pesticide-heavy environments can increase cancer risk by up to 150%. Conducted by scientists from the Institut Pasteur, University of Toulouse, and others, the research utilized environmental monitoring and cancer registry data in Peru, a country with significant agricultural activity and social inequalities. The study found that certain populations, particularly Indigenous and rural communities, are exposed to around 12 different pesticides at elevated levels. By mapping pesticide dispersion from 2014 to 2019 and comparing it with health data from over 150,000 cancer patients, researchers established a clear correlation between high pesticide exposure and increased cancer rates. The findings challenge traditional safety assessments that evaluate individual chemicals in isolation, suggesting that combined exposures may pose greater risks. The study emphasizes the need for updated health policies that consider real-world environmental conditions and their impact on vulnerable populations globally.
