“…This disparity could be in part related to Native American people predominantly residing in rural areas and on reservations, which are known for insufficient health care infrastructure, including availability of mammography 22 . The Indian Health Services, a major health care provider in many rural regions and reservations, is also chronically underfunded 23 and limited in expanding cancer screening services, including mobile units, which contribute to mammography screening prevalence in Native American women 24 . The accessibility to digital mammography was also lower among non‐Hispanic White women compared with other racial/ethnic groups, except the Native American population.…”

“…22 The Indian Health Services, a major health care provider in many rural regions and reservations, is also chronically underfunded 23 and limited in expanding cancer screening services, including mobile units, which contribute to mammography screening prevalence in Native American women. 24 The accessibility to digital mammography was also lower among non-Hispanic White women compared with other racial/ethnic groups, except the Native American population. This is likely related to the settlement patterns of the non-Hispanic White population, whose proportion is larger in rural and suburban areas compared with other racial/ethnic groups, and where travel times to mammography might be longer than in more urban areas.…”

Background: Examining temporal and spatial diffusion of a new technology, such as digital mammography, can provide important insights into potential disparities associated with access to new medical technologies and how quickly these technologies are adopted. Although digital mammography is currently a standard technology in the United States for breast cancer screening, its adoption and geographic diffusion, as medical facilities transitioned from film to digital units, has not been explored well. Methods: This study evaluated the geographic diffusion of digital mammography facilities from 2001 to 2014 in the contiguous United States (excluding Alaska and Hawaii) and estimated the geographic accessibility to this new technology for women aged ≥45 years at the census tract level within a 20-minute drivetime by population density, rural/urban residence, and race/ethnicity. The number of mammography units by technology type (film or digital) and density per 10,000women were also summarized. Results:The adoption of digital mammography advanced first in densely populated regions and last in remote rural areas. Overall, proportion of digital mammography units increased from 1.4% in 2001 to 94.6% in 2014, but since 2008, there was a decline in density of units from 2.31 per 10,000 women aged ≥45 years to 1.97 in 2014. In 2014, approximately 87% of women aged ≥45 years in the contiguous United States had accessibility to digital mammography, but this proportion was substantially lower for Native American women (67%) and rural residents (32%). Conclusion:Understanding the diffusion of and accessibility to digital mammography may help predict future medical technology diffusion and assess its role in geographic differences in cancer diagnosis and treatment.

“…Innovative programs designed to improve screening in the Northern Plains, such as Minnesota’s Intertribal Colorectal Cancer Council and the Wisdom Steps program, appear to have driven positive change and could be used as models in other tribal regions with a high CRC burden 188 . In addition, mobile mammography was used by the Great Plains IHS from 2005 to 2017 to reduce long travel times to screening mammography among American Indian women 189,190 . At the federal level, the CDC’s National Breast and Cervical Cancer Early Detection Program partners with tribal groups to increase access to screening and diagnostic services for Native women 191…”

American Indian and Alaska Native (AIAN) individuals are diverse culturally and geographically but share a high prevalence of chronic illness, largely because of obstacles to high-quality health care. The authors comprehensively examined cancer incidence and mortality among non-Hispanic AIAN individuals, compared with non-Hispanic White individuals for context, using population-based data from the National Cancer Institute, the Centers for Disease Control and Prevention, and the North American Association of Central Cancer Registries. Overall cancer rates among AIAN individuals were 2% higher than among White individuals for incidence (2014 through 2018, confined to Purchased/Referred Care Delivery Area counties to reduce racial misclassification) but 18% higher for mortality (2015 through 2019). However, disparities varied widely by cancer type and geographic region. For example, breast and prostate cancer mortality rates are 8% and 31% higher, respectively, in AIAN individuals than in White individuals despite lower incidence and the availability of early detection tests for these cancers. The burden among AIAN individuals is highest for infection-related cancers (liver, stomach, and cervix), for kidney cancer, and for colorectal cancer among indigenous Alaskans (91.3 vs. 35.5 cases per 100,000 for White Alaskans), who have the highest rates in the world. Steep increases for early onset colorectal cancer, from 18.8 cases per 100,000 Native Alaskans aged 20-49 years during 1998 through 2002 to 34.8 cases per 100,000 during 2014 through 2018, exacerbated this disparity. Death rates for infection-related cancers (liver, stomach, and cervix), as well as kidney cancer, were approximately two-fold higher among AIAN individuals compared with White individuals. These findings highlight the need for more effective strategies to reduce the prevalence of chronic oncogenic infections and improve access to high-quality cancer screening and treatment for AIAN individuals. Mitigating the disparate burden will require expanded financial support of tribal health care as well as increased collaboration and engagement with this marginalized population.

“…Since access and transportation are issues for many minority and low SES communities, breast imaging providers should consider using mobile mammography units to reach both urban and rural communities with limited access or difficulty with transportation. Mobile mammography units have previously been shown to increased adherence to screening in American Indian women in rural settings, a group that has not seen as decline in breast cancer mortality like other groups did with the advent of screening [5] . In addition to screening mammography, Nguyen and colleagues also advocate for equal access to advance imaging technologies, such as screening MRI and ultrasound, which suffer from the same barriers to access in these populations [6] .…”
