Abstract
Lung cancer is a major contributor to mortality worldwide, yet late-stage diagnoses remain frequent due to inadequate public knowledge. This study aimed to assess lung cancer awareness, perceived risks, and symptom recognition among suburban residents in Yogyakarta, Indonesia, to provide data for public health initiatives. The research utilized a cross-sectional design, enrolling 100 individuals aged 18 to 80 from the Kasihan 1 Community Health Center area through consecutive sampling. Participants were given a validated questionnaire regarding their knowledge of lung cancer, its risk factors, and associated symptoms. Descriptive statistical analysis revealed that 63% had moderate knowledge, 22% exhibited good knowledge, and 15% showed poor knowledge. While 76% recognized lung cancer, 55% incorrectly considered it rare, and only 35% were informed about early screening opportunities. Participants demonstrated a strong awareness of active smoking (85%) and passive smoke exposure (82%), yet displayed limited knowledge of environmental carcinogens such as asbestos (35%) and genetic risks (49%). Most could identify key symptoms like shortness of breath (77%), chronic cough (76%), and chest pain (70%). The results highlight significant gaps in understanding non-tobacco-related risks and preventive measures, influenced by socioeconomic factors and local lifestyle habits. Overall, suburban residents show critical blind spots regarding non-behavioral risks for lung cancer, underscoring the need for enhanced primary care education and subsidized screening programs to promote early detection.
