Okay, so the risk of pesticide residues is low. The choice of organic food is one that you should decide for yourself. Eating organic foods is a lifestyle choice. Even organic foods contain natural pesticides usually in larger amounts than the laboratory versions.
Cost is another factor.
Switching to organic on a national level will drive up the price of fruits and vegetables. Reducing one risk can sometimes create another risk. Due to high prices of organic foods, people would eat fewer fruits and vegetables. If cheaper fruits and vegetables aren't available, their risk of cancer leaps far beyond the risk of pesticide residue. For example, scrubbing fruits and vegetables washes away much of the pesticide residue, if there is any present.
