AACR Cancer Disparities Progress Report 2026

Advances in cancer prevention, early detection, and treatment have led to substantial improvements in cancer outcomes in the United States over the past several decades. Despite this progress, these gains have not been equitably distributed, and many populations continue to experience a disproportionate burden of cancer. Persistent disparities, rooted in structural inequities, social disadvantage, and unequal access to health care, remain a major challenge to achieving health equity. The American Association for Cancer Research (AACR) Cancer Disparities Progress Report 2026 highlights both the progress made toward reducing cancer disparities and the critical gaps that remain. Addressing these disparities will require coordinated efforts across research, clinical care, public health, and policy to ensure that advances in cancer science benefit all populations.
