Health Disparities program, which is launching a major new effort to understand and address inequities associated with two leading causes of death in the United States: cancer and heart disease.
Behavioral scientist Beti Thompson, Ph.D., a member of the Public Health Sciences Division of the Hutchinson Center whose research focuses largely on improving cancer screening and prevention within the Hispanic community, is the principal investigator of the Hutchinson Center-based initiative. The research will range from exploring ways to improve mammography screening rates among Seattle-area Latinas to understanding the relationship between dietary patterns and risk of obesity in Hispanic women. The research will also examine the interplay of risk factors and the biology of breast cancer in this population.
Breast cancer is the most common cancer among U.S. Hispanic women. While the incidence of the disease among Latinas is lower than that of non-Hispanic white women (83.5 per 100,000 women versus 147.3 per 100,000 women), as they adopt the practices of mainstream U.S. culture, their risk for breast cancer increases. "Once Latinas come to live in this country, within a generation their risk of breast cancer increases tremendously and approaches that of non-Hispanic whites, so we think something about their lifestyle before they immigrate to the U.S. protects them. It is important to find out what this is so that we can encourage Latinas to make behavioral decisions that foster a protective effect against breast cancer," Thompson said. Latinas also have lower five-year survival rates for the disease as compared to non-Hispanic white women because they are likely to be diagnosed with later-stage disease and because they are at increased risk for breast cancers with a poor prognosis.
As such, the research will also explore the genetics and biology of Latina breast cancer to try to identify what makes these women more susceptible than non-Hispanic white women to particularly aggressive, treatment-resistant forms of the disease. The long-term goal of the project is to understand the precursors of breast cancer in Latinas, understand the types of breast cancer found in this population, and develop and implement a comprehensive screening program to improve early detection of the disease.
