The Breast & Cancer Prevention

Breast Cancer Prevention Information - Risks You Can Change

To prevent breast cancers, scientists look for risk factors (anything that increases your chance of developing cancer) and protective factors (anything that decreases your chance of developing cancer) starting even before birth. We can't change the genes we inherit or our age. However, some risk factors for cancer can be avoided, such as smoking.

Avoiding risk factors and increasing protective factors may lower your risk but it does not mean that you will not get breast cancer. ZBC focuses on individual and community behaviors and environments that we can change.

The Breast Biologues

The Breast Biologues: A biology dialogue about breast cancer and the environment is a 15-minute animated video premiered in November 2010. Narrated by Emmy Award-winning actor Peter Coyote, The Breast Biologues uses time-lapse imaging to explain how the normal breast develops and how exposures to potential cancer-causing chemicals during specific periods of development might influence future breast cancer risk. In addition, comic books based on the video are available in EnglishSpanish, and Vietnamese and can be used in conjunction with the video or on their own. The comic books discuss the biology of the breast and latest BCERP research.
