P2.04B.10 Leveraging High Mammography Screening Prevalence to Increase Lung Cancer Screening Among Women - A Geospatial Perspective

Back to course

Pdf Summary

The document discusses a study aiming to enhance lung cancer screening among women by leveraging the prevalence of mammography screenings. Researchers from the American Cancer Society, including Liora Sahar, PhD, and colleagues, have utilized a geospatial approach to explore whether women who undergo mammograms could also be encouraged to participate in lung cancer screenings, especially those at high risk.<br /><br />The study's methodology involved mapping the current infrastructure of mammography and lung cancer screening facilities across the United States. Researchers used databases like the U.S. Food & Drug Administration and the American College of Radiology to identify these facilities. They assessed proximity between mammography and lung cancer screening sites at varying distances (0, 0.5, and 1 mile) and analyzed this data using rural and urban classifications from census data. <br /><br />The analysis revealed that a significant portion of mammography facilities is located near lung cancer screening sites, particularly in urban areas. The study assessed two geospatial methods for evaluating service areas and estimated the number of women aged 50-74 who could be reached for lung cancer screening based on their proximity to these facilities. Using Method 1, the researchers estimated the number of eligible women for lung cancer screening who already used mammography services.<br /><br />Key findings indicate that over 30 million women aged 50-74, particularly in urban areas, can potentially be encouraged to undergo lung cancer screenings. The study highlights the opportunity to reduce barriers to lung cancer screening by identifying priority locations for intervention, integrating geographic data, and leveraging the widespread presence of mammography facilities. This approach could lead to better identification of women at risk and subsequent referrals to lung cancer screening facilities.
