Study Suggests Link Between DDT and Breast Cancer
Article in the L.A. Times -- Study suggests DDT, breast cancer link, by Marla Cone. Here's an excerpt:
Women heavily exposed to the pesticide DDT during childhood are five times as likely to develop breast cancer, a new scientific study suggests.
For decades, scientists have tried to determine whether there is a connection between breast cancer and DDT, the most widely used insecticide in history. The UC Berkeley research, based on a small number of Bay Area women, tested a theory that the person's age during exposure was critical, and provided the first evidence of a substantial effect on breast cancer.
"There was very broad exposure to this pesticide, and with this study, we have evidence that women exposed when young were the most affected," said Barbara A. Cohn, director of UC Berkeley's Child Health and Development Studies, who led the study of 129 women. "If this finding holds up, those who were young and more highly exposed could be the women at greatest risk."
Women born between 1945 and 1965 were most likely to have been heavily exposed as children to DDT, which was sprayed throughout the United States to kill mosquitoes and other insects. DDT use began in 1945, peaked in 1959 and was banned nationwide in 1972 because it was building up in the environment.
