Geographic Disparities in Mammogram Uptake Highlight Screening Gaps

A comprehensive analysis of over 100 million U.S. insurance claims reveals that while most eligible women are receiving mammograms, geographical disparities in screening rates suggest significant gaps, according to research conducted by Motive Medical Intelligence.

Breast cancer ranks as the second most common cancer and cause of cancer death among American women. Regular mammograms are crucial for early detection, yet the extent of underuse of screening services varies significantly depending on location. The analysis reports that states such as North Dakota and Michigan lead in screening rates, with underuse as low as 15%, whereas Nevada reports rates as high as 29%.

Current guidelines from the U.S. Preventive Services Task Force recommend biennial mammograms for women aged 40 to 74. The American Cancer Society suggests annual screenings beginning at age 40 for women at average risk. Adhering to these guidelines can potentially reduce breast cancer mortality, with early detection leading to a five-year survival rate exceeding 99% for early-stage diagnoses.

Despite the clear benefits of regular screening, disparities persist. Areas with higher rates of underuse include Arkansas, Alabama, and Nevada, with common underuse rates around 26-29%. Maryland ranks among the better-performing states, ranking alongside others with 19% or less underuse.

The Centers for Disease Control and Prevention (CDC) has indicated that many across the U.S. do not participate in preventive health services, including mammography. The disparities in mammogram utilization highlight a concerning aspect of healthcare provision, where factors such as sociocultural, environmental, and even medical professional practices contribute to these gaps.

Chief Medical Officer at Motive, Dr. Rich Klasco emphasized, "Mammography is one of the most cost-effective tools we have for reducing breast cancer mortality. When eligible women are not screened, we lose the chance to detect breast cancer at its earliest and most treatable stage." This sentiment underscores the urgent need for addressing inequalities in mammography access and adherence to evidence-based guidelines.

Julie Scherer, Ph.D., who led the study, remarked on the perplexing nature of these geographical variations, stressing the importance of equitable access to mammograms nationwide, given their long-standing status as a standard of care.

The findings highlight the need for targeted interventions and improved adherence to mammography guidelines across all states to bridge these troubling gaps in breast cancer prevention.
