Addressing Cancer Disparities in Underrepresented Communities

Cancer does not affect all Australians equally. Aboriginal and Torres Strait Islander peoples and African Australian communities face significantly higher cancer mortality rates than the general population, despite cancer being one of the most preventable and treatable diseases when caught early. Understanding why these disparities exist — and what can be done about them — is at the heart of Precision Digital Health's mission.

1. Understanding Cancer Disparities

A cancer disparity refers to a difference in the incidence, prevalence, mortality, or survival of cancer between population groups. In Australia, these disparities are stark and well-documented, yet they remain insufficiently addressed by mainstream health policy and practice.

1.1  Aboriginal and Torres Strait Islander Peoples

Aboriginal and Torres Strait Islander Australians are diagnosed with cancer at younger ages and have significantly lower survival rates than non-Indigenous Australians. They are more likely to be diagnosed at an advanced stage, when treatment options are more limited and outcomes are poorer. For cancers such as lung, liver, and cervical cancer, the mortality gap is particularly pronounced.

These disparities are not the result of biological difference alone. They reflect the ongoing impact of colonisation, dispossession, and systemic disadvantage — including limited access to culturally safe healthcare, geographic isolation, and deep-seated mistrust of health institutions.

1.2  African Australian Communities

African Australians, many of whom arrived in Australia as refugees from countries including South Sudan, Somalia, Ethiopia, and Eritrea, face a unique set of cancer-related challenges. Limited familiarity with Australian screening programs, language barriers, and cultural beliefs around cancer — including stigma and fatalism — can delay diagnosis and treatment.

In some African cultures, cancer is associated with shame or is seen as a death sentence, discouraging people from seeking screening or disclosing symptoms. Community education delivered by trusted cultural peers is essential to changing these narratives.

2. Barriers to Cancer Screening and Early Detection

Early detection is the single most powerful tool in reducing cancer mortality. Yet for underrepresented communities, accessing cancer screening is far from straightforward.

2.1  Geographic Barriers

Many Aboriginal communities in remote and regional Australia are located far from screening facilities. Mobile screening services have helped, but gaps remain. For urban Aboriginal peoples and African Australians, transport costs, work commitments, and unfamiliarity with how to access services can be equally significant barriers.

2.2  Cultural and Language Barriers

Screening programs and health communications are predominantly delivered in English and designed for mainstream Australian audiences. For people from African backgrounds or communities where English is a second language, these materials may be inaccessible. Cultural concepts around modesty, body, and health can also create discomfort with certain screening procedures, particularly for women undergoing cervical or breast screening.

2.3  Systemic Mistrust

For Aboriginal and Torres Strait Islander peoples, historical experiences of medical mistreatment — including forced sterilisation, removal of children, and unethical research practices — have created generational mistrust of health institutions. For African refugees, experiences of trauma, conflict, and healthcare systems associated with harm create similar reluctance. Overcoming this mistrust requires sustained, community-led relationship building rather than one-off health promotion campaigns.

3. Strategies for Reducing Disparities

3.1  Culturally Safe Screening Programs

Screening programs must be redesigned with cultural safety at their core. This means employing Aboriginal and African community health workers, offering services in community languages, conducting outreach through trusted community networks including churches, mosques, and community organisations, and designing physical spaces that feel welcoming and safe.

3.2  Community Education and Awareness

Myth-busting and cancer literacy programs delivered by community members in their own languages are among the most effective tools for increasing screening participation. Peer health educators who share the same cultural background as the communities they serve can communicate messages in ways that resonate, build trust, and encourage action.

3.3  Policy and Funding Reform

Addressing cancer disparities requires sustained political will and dedicated funding. This includes funding for Aboriginal community controlled health organisations, investment in culturally adapted health resources, and policies that mandate culturally safe care across all health services.
