Finding the Causes of Cancer
The Brian Lehrer Show | Feb 10, 2015
Dr. Barbara Cohn, epidemiologist and director of the Child Health and Development Studies, a program of the Public Health Institute, tests pregnancy blood to see if environmental chemical exposure in utero eventually results in breast cancer in the child. She explains the links she's found, and what they tell us about cancer prevention. She is joined by Dr. Linda Birnbaum, director of the National Institute of Environmental Health Sciences (NIEHS), one of the National Institutes of Health (NIH).
