A major new study finds that living in pesticide-heavy environments could raise cancer risk by up to 150%, even when the chemicals are considered “safe” on their own. The research suggests these mixtures may silently damage cells years before cancer appears.
A major new study published in Nature Health has found a strong connection between environmental exposure to agricultural pesticides and an increased risk of cancer. By combining environmental monitoring, national cancer registry data, and biological research, scientists from the IRD, Institut Pasteur, University of Toulouse, and the National Institute of Neoplastic Diseases (INEN) in Peru provide new insight into how pesticide exposure may contribute to the development of certain cancers…
