Significant Reduction in Cancer Mortality
Cancer death rates in the United States have decreased significantly over the past 35 years, with a reduction of 35%. The American Association for Cancer Research highlighted this drop in a report published, noting that nearly 5 million cancer deaths have been prevented since 1991. Increased screening and improvements in treatments are primary factors contributing to this achievement.
Unequal Progress Across Populations
Despite overall progress, disparities persist. African American and American Indian/Alaska Native communities experience the highest cancer mortality rates. Mariana Stern, chair of the report and professor at the Keck School of Medicine, emphasized the unequal incidence and mortality for several cancers among these groups.
Racial Disparities in Cancer Mortality
Historically, Black Americans have faced higher cancer death rates compared to white Americans, although this gap has narrowed recently. Black individuals are about twice as likely to die from cancers such as multiple myeloma, stomach, prostate, and gallbladder compared to white individuals. Breast cancer mortality rates are also 35% higher in Black women than in white women. Colorectal cancer, noted for its increase among those under 50, similarly shows higher death rates among Black and American Indian/Alaska Native populations.
Screening and Prevention Challenges
Effective screening, such as colonoscopies, significantly reduces colorectal cancer mortality. The AACR report notes that screening has contributed to averting 79% of colorectal cancer deaths. Average-risk individuals should begin screening at 45, yet screening rates remain lower in non-white populations. In 2023, only 53% of Hispanic people and 57% of Asian and American Indian/Alaska Native individuals were current with screenings, compared to 67% of white individuals.
“A lot of people are under the misconception that they don’t need to get a colonoscopy until their mid-40s,” Alex Valdez, diagnosed with colorectal cancer at 38.
Valdez’s experience underscores the importance of early screenings, especially for individuals with existing conditions. Effective screenings aid in detecting cancer early, easing treatment efforts.
Access Disparities: Screening and Vaccine Availability
Cervical cancer screening rates are lower among Asian and Hispanic women compared to white women. Dr. Sarah Kim of Memorial Sloan Kettering Cancer Center highlights the difficulties faced by socially disadvantaged groups in accessing regular screenings. Cervical cancer rates are 32% higher in impoverished counties, with death rates 49% higher. The HPV vaccine provides a preventive measure against cervical cancer, accessible without prescription from pharmacies.
Factors Affecting Cancer Disparities
Systemic racism and socio-economic conditions contribute to disparities in cancer outcomes. Quality of treatment and access to healthcare remain critical challenges for minority and underserved populations. Patient navigators have proven effective in improving healthcare access, helping patients efficiently manage their treatment pathways. Dr. Kim supports these efforts through collaboration with navigators during her residency.
Funding Concerns
Future support for programs addressing healthcare disparities might be at risk due to proposed budget cuts, including reductions to the NIH and elimination of the National Institute of Minority and Health Disparities. These actions could jeopardize the strides made in reducing cancer disparities.
