A Silent Spring Institute study identifies hundreds of chemicals tied to possible breast cancer risk. Many are hidden in pesticide formulations and receive less safety testing.
More than 480 chemicals used in pesticide formulations have been identified as possible breast cancer risks in a Silent Spring Institute study. The list includes active substances and so-called inert ingredients, which often receive less extensive safety testing. Researchers say people encounter these compounds through food, water, household products and the wider environment.
The findings do not prove that these substances caused breast cancer in exposed individuals. Alejandro Pérez Fidalgo of INCLIVA and the Spanish Society of Medical Oncology said exposure levels and personal predisposition remain decisive factors. In his view, the study should encourage people to reduce exposure without causing public alarm.
