Worldwide, breast cancer is the leading cause of cancer death in women. Although the United States and Western Europe have a five-fold higher number of new cases of breast cancer compared with Africa and Asia, [5]  since 1990, the death rate of breast cancer has declined by 24% in the United States (as well as other countries in Western Europe). This may be due to increased use of screening mammography and of adjuvant chemotherapy therapy. [5]

Given the high incidence and mortality of breast cancer, defining the risk factors for breast cancer has significant clinical value. Physicians can use this information to work with patients to minimize modifiable factors, and to determine appropriate screening procedures.
