Limited screening mammography, workforce shortages, and underfunded healthcare systems contribute to late diagnoses and poorer outcomes. Social and cultural factors, including historical trauma and medical mistrust, further hinder care. Data on breast cancer topics for AI/AN is limited and often compromised by misclassification and underrepresentation. The Indian Health Service (IHS) plays a crucial but underfunded role in providing care, often insufficient to meet the complex needs of AI/AN women, especially those living in urban areas.  \nSummary As Indigenous surgeons working with AI/AN communities, we applied our perspectives to a comprehensive review of the literature. To reduce disparities, research must prioritize Indigenous leadership, respect tribal sovereignty, improve data accuracy, and foster equitable collaborations that center AI/AN priorities.  \nDefinitions The United States (US) Census Bureau defines American Indian and Alaska Natives (AI/ANs) as persons with origins from the Indigenous peoples of the Americas who maintain tribal affiliation and/or community attachment. Common terms for AI/ANs today include Native, Native American, Indigenous, First Nations, Native Hawaiian, Pacific Islander, among others. The most appropriate phrasing would be to use the specific tribe’s self-designated name in that tribe’s native language when possible. However, for simplicity and the purposes of this manuscript, we will use the term AI/AN.  \ntreated with mastectomy (41% versusKeywords Breast cancer · American indian · Alaska native · Native american · Cancer disparities  \nIntroduction  \nAmerican Indian and Alaska Native (AI/AN) populations represent over 574 federally recognized tribes across the US, each with its own distinct culture, language, and traditions.

The origins of these disparities lie in the historical legacy of colonization, forced relocation, cultural erasure, and broken federal treaties, which have collectively undermined the social, economic, and physical well-being of Native communities for generations. Today, AI/ANs experience higher rates of poverty, lower access to education and preventive services, and some of the lowest life expectancies of any racial or ethnic group in the US [1] . Nearly 60–70% of AI/ANs live in urban areas—often outside of tribal lands—where access to culturally competent healthcare resources is severely limited [2, 3] . These structural inequities set the stage for disproportionate disease burdens, including a rising incidence of cancer.  \nIn 2024, approximately 310,720 new cases of breast cancer were identified among women in the US.
