TUESDAY, Oct. 1 (HealthDay News) -- White women 40 and older have traditionally had the highest rates of breast cancer in the United States, but rising rates among blacks have narrowed the gap in recent years, according to a new American Cancer Society report.
"This convergence of rates is being driven by steady rates among white women and a slow increase in recent years among African-American women," said report co-author Carol DeSantis, an epidemiologist in the society's Surveillance and Health Services Research Group.
From 2006 through 2010, breast cancer rates increased 0.2 percent among black women but remained stable among whites, researchers found. White women still have more cases of breast cancer, however, with about 127 cases per 100,000 compared with 118 cases per 100,000 black women.
But deaths from breast cancer are more common among blacks, according to the report published Oct. 1 in CA: A Cancer Journal for Clinicians.
The gap is closing most among women aged 50 to 59 years old, and the reasons why aren't clear, the researchers say.
Another expert voiced concern.
"Even with all the attention and awareness raised around breast cancer, the incidence of the disease holds steady," said Dr. Stephanie Bernik, chief of surgical oncology at Lenox Hill Hospital in New York City.
"Although the incidence haven't declined, we have made strides in the effort to improve the survival rate," she noted. "Death rates have declined by 34 percent since 1990. However, not all ethnic groups are enjoying this improved survival."
The death rate during the study period was 30.8 per 100,000 among black women compared to 22.7 per 100,000 among whites, the reports says.
Blacks have a worse prognosis stage for stage, and the incidence of breast cancer in this group in increasing, Bernik said.
"The reasons for this increase among African-American women are unclear, but may be linked to socioeconomic status and barriers to treatment," she said.
Bernik added that improvement in the survival rate is encouraging, but said more work needs to be done to prevent the disease from starting in the first place.
