(HealthDay News) — Incidence rates of breast cancer among U.S. women are stable for most racial/ethnic groups, but are increasing for African-American women, with the incidence rates converging for whites and African-Americans, according to a study published online Oct. 1 in CA: A Cancer Journal for Clinicians.

Carol DeSantis, M.P.H., from the American Cancer Society in Atlanta, and colleagues reviewed female breast cancer statistics for 2013 in the United States.

The researchers note that, in 2013, among U.S. women, about 232,340 new cases of invasive breast cancer are projected to occur, as well as 39,620 breast cancer deaths. In the United States, one in eight women will develop breast cancer in her lifetime.

From 2006 to 2010, the incidence rates of breast cancer remained stable for whites, Asian-Americans/Pacific Islanders, and American Indians/Alaska Natives, while they increased slightly for African-American women and decreased among Hispanic women. The incidence rates are converging for white and African-American women, especially among those aged 50 to 59 years. Breast cancer death rates decreased 34% from 1990, and the decline was seen in almost all racial/ethnic groups.

“Continued progress in the control of breast cancer will require sustained and increased efforts to provide high-quality screening, diagnosis, and treatment to all segments of the population,” the authors write.
