The Impact of Health Literacy Upon Lung Cancer Screening Beliefs among Residents of Neighborhood Adjacent to Refinery Oil at Basra City

Abstract Background and Objectives: The closeness of residential neighborhoods to oil refineries and petrochemical plants in these areas has heightened the community’s exposure to dangerous air pollutants. This study aimed to investigate the impact of health literacy upon lung cancer screening beliefs among residents of neighborhood adjacent to a refinery oil. Materials and Methods: A cross-sectional study design using nonprobability convenience sampling was applied, employing descriptive, correlational, and regression analyses to explore potential predictors of the sampling technique from October 10, 2024, to March 20, 2025. The data collected were organized and analyzed using SPSS version 26, and the results were presented descriptively and inferentially. Results: The findings of the current study showed that age, duration of residence in close industrial zones, and socioeconomic status significantly influenced perceptions of lung cancer screening. Members with higher cancer health literacy (CHL) exhibited more positive attitudes. Barriers included fear, stigma, and misconceptions regarding screening benefits and purpose, with evident gaps in cancer-related knowledge. Conclusion: Low CHL in areas with industrial fragments contributes to negative screening beliefs, late diagnosis, and poor participation. Addressing literacy gaps is vital for improving early detection and outcomes.
