Cancer death rates in the United States have fallen to historic lows, thanks to advances in screening, early diagnosis, and treatment. However, significant racial and ethnic disparities persist, with Black and American Indian/Alaska Native populations continuing to experience the highest cancer incidence and mortality rates, according to a new report published by the American Association for Cancer Research (AACR).
Researchers attributed much of the decline in cancer deaths to improved screening programmes, earlier detection, and major treatment breakthroughs that have increased survival rates for cancers once considered far more deadly.
Despite this progress, the report warns that the benefits have not been shared equally across all communities.
Black and American Indian/Alaska Native populations continue to bear a disproportionate burden of cancer, reflecting longstanding inequalities in prevention, access to healthcare, diagnosis, and treatment.
“African American communities and American Indian and Alaska Native populations have the highest overall cancer death rates of any U.S. racial or ethnic group, and this means higher incidence and mortality for multiple cancers,” the report’s chair said.
While researchers noted that the mortality gap between Black and white populations has narrowed in recent years, substantial disparities remain.
Black populations are still about twice as likely to die from multiple myeloma as well as cancers of the stomach, prostate, and gallbladder compared with white populations. Breast cancer outcomes also remain unequal, with Black women continuing to experience significantly higher death rates.
According to the report, these disparities are driven by more than biological factors alone. Researchers linked them to unequal access to healthcare, delayed diagnoses, financial barriers, differences in treatment quality, and broader social and economic conditions that influence health outcomes.
One area of growing concern is colorectal cancer, which is increasingly being diagnosed in younger adults.
Although colorectal cancer deaths have declined due to expanded screening efforts, experts caution that many communities remain underserved. The report estimates that screening programmes have prevented nearly 79 per cent of colorectal cancer deaths by detecting and removing precancerous polyps before they develop into cancer.
Current guidelines recommend that people at average risk begin colorectal cancer screening at age 45. However, screening uptake remains uneven across different populations.
Data cited in the report showed that in 2023, only 53 per cent of Hispanic populations and 57 per cent of Asian and American Indian/Alaska Native populations were up to date with colorectal cancer screening, compared with 67 per cent among white populations.
Researchers also observed a rise in early-onset colorectal cancer cases, particularly among Hispanic populations.
The report further highlighted persistent disparities in cervical cancer. Despite the availability of HPV vaccines and screening programmes, cervical cancer rates remain significantly higher among women living in poorer communities.
Researchers found that cervical cancer incidence was 32 per cent higher in poorer counties than in wealthier areas, while death rates were nearly 49 per cent higher.
Healthcare specialists say barriers such as cost, transportation challenges, limited access to routine healthcare, and competing life responsibilities continue to hinder participation in screening programmes.
“Cervical cancer remains a problem,” one cancer specialist noted. “Especially for patients who don’t have access to care for a multitude of reasons.”
The report also pointed to broader structural challenges, including longstanding social and economic inequalities that continue to shape cancer outcomes.
Patients from racial and ethnic minority groups, low-income households, and medically underserved communities were found to be less likely to receive recommended cancer treatment despite major advances in care.
Researchers highlighted patient navigation programmes as one effective strategy for improving outcomes. These programmes help patients schedule appointments, understand treatment plans, and overcome obstacles that may prevent them from receiving care.
However, concerns remain about whether such programmes will continue to receive adequate funding.
While celebrating decades of progress in the fight against cancer, researchers stressed that declining death rates alone cannot be the sole measure of success.
They argued that closing gaps in screening, prevention, and access to quality treatment will be essential to ensuring that future reductions in cancer deaths benefit all populations equally.
