Exercise and Breast Cancer


By Staff Reports

(Victor Valley)– From the U.S. Department of Health and Human Services, I’m Ira Dreyfuss with HHS HealthBeat.

African-American women who exercise regularly seem to have a lower risk of breast cancer. Boston University researchers found this in 16 years of follow-up of more than 44,000 African-American women in the Black Women’s Health Study.

Lead researcher Lynn Rosenberg:

“Women who exercised seven or more hours a week had a 25 percent lower incidence of breast cancer than sedentary women.”

Exercisers did things like swimming, running, aerobics and basketball. Women who did brisk walking also benefited – but not women who walked at a normal pace.

These findings for black women are in line with what other researchers had found earlier in white women.

The study in the journal Cancer Epidemiology Biomarkers & Prevention was supported by the National Institutes of Health.
