Do pesticides cause cancer in people exposed to low doses of pesticides over a period of time?

No. As used, pesticides do not cause cancer.

Before a pesticide product can be registered and marketed, it must first be evaluated as to its potential risks, including any risk of causing cancer. Only products determined by EPA to have met the Agency’s rigid testing requirements can be registered by the EPA. There is no specialty pesticide on the market known to cause cancer in humans.

The American Medical Association’s Council on Scientific Affairs states that there is only conjectural evidence at best that pesticides may be carcinogenic. Dr. Bruce Ames, University of California at Berkeley, states, “There is no convincing evidence from either epidemiology or toxicology that pesticides are of interest as causes of human cancer.”
