Fifty Thousand Strong: The Sister Study, with Dale Sandler

EHP: The Researcher's Perspective

In the United States more than 40,000 women die of breast cancer each year, and almost 200,000 women develop the disease. Although survival rates have improved and risk factors have been identified, the causes of breast cancer remain unclear. In 2004 researchers at the National Institute of Environmental Health Sciences (NIEHS) began recruiting sisters of breast cancer patients for a study to explore environmental and genetic factors behind this disease. Now that more than 50,000 women have been recruited, Dale Sandler discusses what comes next for the Sister Study. Sandler is the principal investigator of the Sister Study and chief of the Epidemiology Branch at the NIEHS. Visit the podcast webpage to download a full transcript of this podcast.
