Cancer health disparities caused by structural inequities are an enormous public health challenge in the United States.

In recent decades, disparities in the burden of certain cancer types have declined among minority populations, but substantial differences in cancer burden remain. Key partners across the cancer care continuum are working together to understand and reduce cancer disparities.

Social drivers of health—which include income, education, housing, and access to care—disparately and adversely affect racial and ethnic minority groups and other medically underserved populations. Policy interventions can mitigate upstream social barriers to care and reduce cancer disparities.

Cancer development is driven by complex interactions among factors inside and outside the cell. Broader social, environmental, and structural conditions can influence biology and contribute to differences in cancer risk, tumor behavior, and treatment response across population groups.

In the US, about 40% of all cancer cases are associated with modifiable risk factors. Built environments disproportionately expose racial and ethnic minority groups and other medically underserved populations to cancer risk factors, including commercial tobacco, pollution, and toxic chemicals.

Persistent gaps in screening uptake and follow-up care disproportionately affect racial and ethnic minority populations and other medically underserved communities. Targeted, evidence-based strategies can improve adherence to recommended screening and follow-up, thereby narrowing long-standing disparities.

Studies show that disparities in outcomes for several cancer types can be substantially reduced when all patients have access to guideline-adherent treatments. Diversifying clinical trials requires health care providers to offer trial options to all patients and eliminate barriers to participation.

Medically underserved populations shoulder a disproportionate burden of survivorship challenges, including late effects of treatment, mental health burdens, and financial toxicity. Patient-centered approaches such as patient navigation, telehealth, and community partnerships can help eliminate this disparity.

A diverse cancer research and care workforce strengthens trust, communication, treatment adherence, research participation, and patient-centered care, while reducing systemic bias and improving outcomes. Long-standing programs have diversified the workforce by supporting students from underrepresented backgrounds.

Investment in federal agencies and programs, promoting an inclusive workforce, increasing equity in cancer screening and follow-up care, and encouraging broader representation in clinical research are all fundamental to addressing cancer disparities.

To reduce cancer disparities, AACR calls upon policy makers to improve collection of disaggregated data for minority groups; increase access and participation in clinical trials; enhance prevention and screening efforts; ensure equitable patient care; and build a more diverse cancer research and care workforce.

Thanks to innovations in science and technology, we are living in an era of unprecedented progress against cancer and are poised to deliver even more transformative breakthroughs for our patients. But we must be equally committed to ensuring that no populations or communities are left behind.

Thanks to decades of research, we are witnessing unprecedented progress against cancer. Yet, these advances have not benefited everyone equally. Access to health care is a fundamental human right, and health care disparities remain among the most profound forms of injustice.
