The Landmark Series: Surgical Oncology Care in Native Americans-The Indian Health Service.

American Indian and Alaska Natives (AI/ANs) are a heterogeneous group of people living throughout the USA with some of the highest cancer incidence and highest cancer-related mortality in the country. This landmark series seeks to highlight cancer care in this population by providing a historical context of the largest healthcare delivery system serving AI/ANs, the Indian Health Service (IHS). We will highlight how the dynamic nature of this population creates unique challenges and the need for dedicated resources to help eliminate cancer care disparities.
