Pesticides Increase Breast Cancer Risk
Exposure to certain pesticides, known as organochlorines, may increase the risk of breast cancer in women. Organochlorines, which are found in agricultural and industrial products, have a weak estrogen-like effect, and play a role in the development of breast cancer. After taking into account other known risk factors for breast cancer, the researchers write that the risk of breast cancer was twice as high in women with the highest (blood) concentrations of dieldrin (an organochlorine) as that in women with the lowest concentrations.
