Pesticide exposure adds to the risk of breast cancer and other forms of reproductive illness. The Endocrine Society has stated that exposure to pesticides may contribute to breast cancer risk and development. Studies shows that pesticides disrupt multiple metabolic pathways, which can prevent the body from properly defending itself against cellular mutations leading to cancer.
The organochlorides in pesticides appear to be at the root of many of the adverse physiological effects. These are the type of pesticide sprayed on strawberries throughout their growth. The regular non-oragnic strawberries in the grocery store have been heavily sprayed with these compounds.
To avoid exposure to agricultural pesticides look for the USDA Organic label on produce as organic certification does not allow for the use of chemical pesticides or herbicides on plant foods for human consumption.
