Pesticides and Agriculture

Exposure to pesticides has been analyzed in many studies of childhood CNS tumors and several studies have investigated exposure to animals and residence on farms as a risk factor. Elevated risks have been found for at least one measure of pesticide exposure in half the studies, more markedly for domestic exposure during pregnancy, although there have also been numerous nonsignificant results and few studies have provided risks for specific histological types [22]. Childhood farm residence and maternal or child exposure to farm animals tended to be associated with higher risk [23]. If the latter associations are real, they might be related to oncogenic animal viruses, but there is also likely to have been a high degree of confounding with pesticide exposure. In the International Adult Brain Tumor Study there was little evidence that gliomas or meningiomas were associated with contact with animals or with occupations involving high levels of contact with animals or humans [24].
