Cancer Prevalence

Cancer is a leading cause of death among American Indian and Alaska Native (AI/AN) populations. Overall, AI/ANs face inequities in cancer prevention and control and have not seen the same level of progress as non-Hispanic whites over the past decades. In many regions, AI/AN cancer rates are significantly higher than rates of non-Hispanic whites, with stagnant or increasing rates for lung, colorectal, and breast cancers.

Cancer prevalence, incidence, and mortality are important indicators of health status for AI/AN populations. AI/AN cancer incidence and mortality rates vary greatly across regions and genders.

Lung Cancer

Lung cancer is the most common cause of cancer death among AI/ANs. Lung cancer incidence and mortality rates are highest in the Northern Plains and Alaska and lowest in the Southwest. Northern Plains women are over two times as likely to die of lung cancer as non-Hispanic whites. Northern Plains men are 1.71 times as likely to die of lung cancer as non-Hispanic whites. Alaska Native men are almost 1.5 times as likely to die of lung cancer as non-Hispanic whites. Southwest AI men and women are one-third as likely to die of lung cancer as non-Hispanic whites.

Colorectal Cancer

Colorectal cancer is the second most common cause of cancer death among AI/AN men and third among women. Alaska Native men are twice as likely as white men to be diagnosed with and die of CRC. Alaska Native women are almost 2.5 times as likely as non-Hispanic white women to be diagnosed with and die of the disease.

Cervical cancer

Northern Plains women are twice as likely to be diagnosed with cervical cancer and 4.15 times as likely as White women to die of the disease.

Breast cancer

Breast cancer is the most frequently diagnosed cancer and a leading cause of mortality among AI/ANs. Over the past decade, breast cancer death rates decreased significantly among white women yet regional and national AI/AN rates were unchanged. AI/AN women continue to have worse survival rates than White women.

Liver cancer

Overall, AI/AN men and women are 2.12 and 2.84 times as likely to die of liver cancer as white men and women, respectively. Northern Plains women were 3.25 times as likely to die of the disease.

AI/AN cancer surveillance data is often limited by small AI/AN population sample sizes, data or population aggregation in national and regional datasets, and lack of culturally appropriate survey methods. Widespread racial misclassification in State Cancer Registries results in underestimation of AI/AN cancer burden. However, these limitations can be reduced through collaborative surveillance efforts among tribal, state, and federal agencies, including Cancer Registry data linkages, using larger AI/AN population sample sizes or oversampling in surveys, use of culturally appropriate survey methods, and development of strong regional and tribal-specific datasets.

Many AI/ANs have high rates of smoking, obesity, physical inactivity, and low rates of cancer screening and consumption of fruits and vegetables. These contributing factors increase cancer risk and form the basis of “winnable battles” that tribal health systems and programs may tackle. Learn more about Cancer Prevention.
