Breast cancer incidence rates in the United States increased by more than 40 percent between 1973 and 1998. In 2008, a woman's lifetime risk of breast cancer is one in eight.

State of the Evidence 2008 is a comprehensive report on the environmental exposures linked to increased breast cancer risk, including natural and synthetic estrogens; xenoestrogens and other endocrine-disrupting compounds; carcinogenic chemicals and radiation.

This exhaustive catalog provides a much more complex picture of breast cancer causation than traditionally accepted, one in which timing, mixtures and dose of environmental exposures interact with genes and lifestyle factors.

The scientific evidence provides the basis to move forward with research and public policy changes that will help reduce our exposure to chemicals and radiation linked to increased breast cancer risk.

Findings

While each study, chemical and exposure source alone doesn't tell the whole story, looking at them together allows us to better understand how to prevent the disease. Learn more about major emerging themes in breast cancer causation through the links below.
