Are pesticides associated with cancer risk?

Pesticides are commonly used inside and outside the home. Evidence from studies of farmers suggests that some pesticides are likely carcinogenic, but the impact of lower levels of exposure is less clear. By collecting information on pesticide exposure through surveys and analysis of carpet dust, we could evaluate the risk of cancer associated with low levels of pesticide exposure. Given their widespread use, even a small increase in risk could have a substantial public health impact.
