In this 15-minute video, renowned cancer researcher Dr. Margaret Kripke of MD Anderson Cancer Center tells the story of why she began to rethink her assumptions about the causes of cancer and the true burden of environmentally-induced cancers.

Dr. Kripke served on the President’s Cancer Panel from 2003 until 2010. It was during that time that the Panel decided to examine the impact of environmental factors on cancer risk. Dr. Kripke learned that of the 80,000+ chemicals on the market in the United States, most are largely unstudied or understudied, and most are unregulated. She realized that exposure to cancer causing chemicals and environmental carcinogens are a widespread and daily occurrence for millions of people in the U.S., and that most people still don’t know this.
