Cancer Screening Interventions in Indigenous Populations: A Rapid Review

Cancer screening is an important component of a cancer control strategy. Indigenous people in Canada have higher incidence rates for many types of cancer, including those that can be detected early or prevented through organized screening programs. Increased participation and retention in cancer screening is critical to improved population health outcomes amongst Indigenous people. This rapid review evaluates cancer screening interventions published in the last six years. Included studies demonstrated increased participation in breast, colorectal, or cervical cancer screening programs in Indigenous populations or showed promise of increased participation based on the factors that influence people’s screening practices, such as knowledge, attitude, or intent to screen. The Preferred Reporting Items for Systematic Reviews guided the search strategy. The review identified 85 articles with 12 meeting the specified criteria: seven studies reported an increase in cancer screening participation and five studies reported improved knowledge, attitude, or intent to screen. The use of multiple culturally appropriate strategies in co-designed studies were the most effective. This review will be used to inform First Nations (FN) populations and Screening Programs in Alberta of potential strategies to address disparities identified through a recent data analysis comparing cancer screening and outcomes between FN and non-FN people.

Barriers to and facilitators of breast, cervical and colorectal cancer screening and cancer screening histories of Métis people in Alberta, Canada

Comprehensive evaluation of cancer screening activities based on individual experiences is urgently needed to address the burden of cancer among Métis people. In this co-designed and co-led study, a cancer screening questionnaire developed for Métis people to evaluate their cancer screening histories and to explore barriers and facilitators to cancer screening was used. Adult Métis Albertans were invited to participate in the anonymous survey through a multi-modal strategy used for community consultations. Descriptive analyses compared responses between regions, age groups and geographic locations. In total, 370 participants who identified as Métis consented and contributed responses between 12 September and 2 December 2022. Female respondents reported higher rates of cervical and breast cancer screening (>94%) and lower rates of colorectal cancer screening (67-78%). Most of the barriers and facilitators were rated as very important, especially access to reliable and accurate information on screening, risks and benefits of cancer screening, explanation of the test results or procedures, trust in their health care provider(s) and health care system and access to a primary health care provider. This study fills a crucial gap that can inform targeted interventions to increase cancer screening awareness and rates among Métis Albertans and reduce their cancer burden.
