Screening-detectable cancers, specifically colorectal, lung, female breast, and cervical cancers, make up a large percentage of cancers among non-Hispanic American Indian/Alaska Native (AI/AN) populations. Incidence rates for these cancers vary by geographic region. The highest incidence rates were seen in the Southern Plains; lung cancer in males and breast cancer in females. The lowest rates in males were observed for lung cancers in the Southwest and for cervical cancer in females in the East.

Purchased/Referred Care Delivery Areas (PRCDA) are counties that contain federally recognized tribal lands or are adjacent to tribal lands. Race classification for the non-Hispanic American Indian/Alaska Native (AI/AN) population is more accurate in these counties.

Data Sources:

Data in this brief come from U.S. Cancer Statistics, the official federal cancer statistics.

U.S. Cancer Statistics incidence data are from population-based registries that participate in CDC’s National Program of Cancer Registries (NPCR) and/or the National Cancer Institute’s Surveillance, Epidemiology, and End Results (SEER) Program and met high-quality data criteria for the 2020 data submission, covering 99% of the U.S. population.
