Breast cancer cases in Asian women have increased since 2005

Cases of breast cancer in U.S. Asian or Pacific Islander women increased an average of 1.4 percent per year between 2005 and 2018, according to data collected by the Centers for Disease Control and Prevention (CDC). That was far more than any other racial or ethnic group.

During about the same time period, cases in White and Hispanic women increased an average of 0.4 percent, while breast cancer cases declined in Black women by an average of 1.3 percent from 2015 to 2018.

CDC suggested the increased incidence of breast cancer may be related to the doubling of obesity rates over the past 30 years.
