Health equity places health inequities in historical and social context and calls for action to address injustice and enhance health. As an ethical and human rights value that drives us to end health inequities, health equality is defined as everyone having a fair and just opportunity to be as healthy as feasible. According to this perspective, structural discrimination and marginalization cause health disparities that can be avoided. If these issues are not resolved, social and economic injustices, bias, and unfavorable outcomes that affect all of us will continue to exist. The idea of cancer health equality recognizes that there is still considerable work to be done to change the social structures and historical momentum that have contributed to different cancer outcomes, and that this work can only succeed if it is done.

In USA, non-Hispanic black women experience a complicated and multifaceted disparity in breast cancer incidence and outcome. It's possible that social, economic, and behavioral variables contribute to discrepancies. Black women are less likely to breastfeed after childbirth, statistically more likely to have diabetes, heart disease, and obesity, all of which are risk factors for breast cancer. Compared to white women, they are more likely to lack adequate health insurance or access to medical facilities, which could have an impact on screening, follow-up treatment, and therapy completion.

It has become evident via more study that biology also plays a part. Black women are more likely to be diagnosed at younger ages and at higher rates with more aggressive subtypes of breast cancer, such as triple-negative breast cancer (TNBC) and inflammatory breast cancer.

The National Institute on Minority Health and Health Disparities (NIMHD) established a research framework to characterize the multiple domains of influence (biological, behavioral, physical environment, sociocultural environment, and health care system) that may act across various levels of influence to impact health. A literature search was conducted using the National Library of Medicine's PubMed search engine. Triple negative breast cancer (TNBC) is a common malignancy in African American women. The incidence of TNBC is higher in women of African ancestry and is associated with overall poor prognosis. This disparity is due to the presence/absence of oncogenes/tumor suppressor genes, mutations and altered signaling pathways that might predispose premenopausal African American women to TNBC. Multiple socioeconomic factors influence the access to standard care, novel treatments and inclusion in clinical trials and contribute to overall prognoses. This review focuses on the epidemiology, molecular alterations, and treatment-related disparities in African Americans with breast cancer.

This poster will elaborate the racial disparity in terms of breast cancer among the African-American women in USA, the reasons and it's effects on health equity.
