Exposure to combination of pesticides increases childhood cancer risk – study

Study on cancer data in US agricultural heartland finds children more at risk than if exposed to just one pesticide

Exposure to multiple pesticides significantly increases the risk of childhood cancers compared with exposures to just one pesticide, first-of-its-kind research finds, raising new fears that children are more at risk to the substances' harmful effects than previously thought.

The study's authors say they are the first to look at the link between exposures to multiple widely used pesticides and the most common childhood cancers. Most research considers pesticides' toxicity on an individual basis, and the substances are regulated as if exposures occur in isolation from one another.
