By cross-referencing this mapping with geodata from more than 150,000 patients diagnosed between 2007 and 2020, the researchers were able to identify areas where people are both more likely to be exposed to pesticides in the environment and more likely to be affected by certain cancers. In these areas, the risk of developing cancer was, on average, 150% higher.

Pesticides and cancer: Study reveals the biological mechanisms behind an environmental health risk
A new study, published in Nature Health, reveals a strong link between exposure to agricultural pesticides in the environment and the risk of developing cancer. By combining environmental data, a nationwide cancer registry, and biological analyses, researchers from the IRD, the Institut Pasteur, the University of Toulouse, and the National Institute of Neoplastic Diseases (INEN) in Peru have shed new light on the role of pesticide exposure in the development of certain cancers.
