Breast cancer is one of the most common cancers affecting American women, and is second only to lung cancer as a leading cause of cancer death in women. The number of breast cancer cases incidence has been on the rise during the past 20 years, while the death rate from breast cancer has decreased slightly in the past five years. The increase in cases is related, in part, to a greater emphasis on screening with routine breast exams and mammography. These screening tools often can detect breast cancer at an earlier -- and more treatable -- stage, which helps explain why the death rate has not increased significantly. The exact cause of breast cancer has not been established, but there are risk factors that may play a role. A risk factor is a trait or behavior that increases a person's chance of developing a disease or makes a person susceptible to a certain condition.

The Race Against Breast Cancer
These women also tend to be at later stages of the disease when they are diagnosed, leaving them few, if any, options for treatment. In the latest study, the researchers, led by Lu Chen from the division of public health sciences at Fred Hutchinson Cancer Research Center, and her colleagues report that not only are African-American women more likely to be diagnosed at later stages with the most aggressive form of the disease, but they are also more likely than white women to be diagnosed at later stages for all types of breast cancer. That strongly suggests that while biology and genes contribute to a heightened risk of cancer, social and cultural factors such as lower incomes may be driving the worse outcomes experienced by these women when they are diagnosed. Studies have shown that African-American, Hispanic and Native American women tend to have less access to screening mammograms, for example.
White women are slightly more likely to develop breast cancer than African American, Hispanic, and Asian women. But African American women are more likely to develop more aggressive, more advanced-stage breast cancer that is diagnosed at a young age. African American women are also more likely to die from breast cancer. Some of these differences in outcomes may be due to less access to mammography and lower quality medical care, as well as various lifestyle patterns eating habits and weight issues for example that are more common in some ethnic groups than in others.
