Health Disparities and Triple-Negative Breast Cancer in African American Women: A Review
View abstract on PubMed
Summary
This summary is machine-generated.Racial disparities in breast cancer are influenced by genetics and socioeconomic factors. Understanding these complex interactions is crucial for developing targeted precision medicine approaches to reduce cancer mortality in African American women.
Area Of Science
- Oncology
- Population Genetics
- Molecular Epidemiology
Background
- Breast cancer disparities show significant correlations with racial and ethnic identity in the U.S.
- African American women experience a higher burden of breast cancer compared to European/white American women.
- Socioeconomic, cultural, and lifestyle factors often confound genetic explanations for these disparities.
Purpose Of The Study
- To elucidate the sources of breast cancer disparities related to racial/ethnic identity.
- To advance knowledge on the pathogenesis of triple-negative breast cancer.
- To inform the national Precision Medicine Initiative.
Main Methods
- Transdisciplinary research combining population genetics, oncology, molecular epidemiology, and behavioral science.
- Analysis of population-based breast cancer mortality rates.
- Investigation of genetic components and hereditary susceptibility.
Main Results
- Higher breast cancer mortality rates observed in African American women compared to white American women.
- Endocrine therapy is less effective in African American women due to higher prevalence of estrogen receptor-negative disease.
- Increased risk of triple-negative breast cancer in African American women suggests genetic contributions from African ancestry.
Conclusions
- Disentangling genetic, socioeconomic, and lifestyle factors in breast cancer disparities remains challenging.
- Epigenetics and allostatic load add complexity to understanding racial/ethnic disparities in breast cancer.
- Oncologic anthropology offers a framework to eliminate breast cancer disparities and advance triple-negative breast cancer research.
