Can organophosphates cause any types of cancer, including leukemia?
We do not know for sure. Some studies in adults and children have linked organophosphate exposure to lymphoma and leukemia. Home pesticide use overall has been linked to childhood cancers such as soft tissue sarcomas, leukemias, and cancer of the brain. The results of these studies are controversial. No studies have definitively linked these exposures with cancer because the exposure is not measured and people usually are not exposed to just the one pesticide being studied. In lab rats, studies of different organophosphates showed more adrenal, thyroid, and pancreatic tumors.
