Knowledge, Attitudes, and Practices Regarding Breast Cancer Screening Among Females in Saudi Arabia

Background: Breast cancer comprises 31.4% of all female cancers in Saudi Arabia (2020 Cancer Registry). Despite free national screening services existing since 2005, mammography utilization remains critically low. This study assessed breast cancer knowledge, attitudes, and practices (KAP) among females in Saudi Arabia and identified independent predictors of screening behavior. Methods: A cross-sectional study (December 2024-February 2025) enrolled 426 females aged ≥20 years from all 13 Saudi administrative regions using a quota-based design combining facility-based and online recruitment. Attitude and barrier domains were adapted from Champion's Health Belief Model Scale (CHBMS), validated in Arabic; knowledge items used validated regional instruments. Knowledge-score reliability: KR-20 = 0.45; attitude subscale: α = 0.74. Binary logistic regression identified independent predictors of screening uptake (outcome: any screening in the preceding five years, coded as screened = 1; not screened = 0). Results: Mean composite knowledge score: 4.51 ± 1.52/7 (KR-20 = 0.45); 54.0% achieved high knowledge (≥5). Mammography uptake was 30.5% overall and 52.2% among women aged ≥40 (n = 136; the recommended target group). Predominant barriers: Fear of diagnosis (83.6%), belief in incurability (76.3%), radiation concern (73.2%), and pain anxiety (72.3%). Logistic regression (χ²(8) = 188.96, p < 0.001; McFadden's pseudo R² = 0.323) identified older age (OR = 1.52; 95% CI: 1.21-1.92), higher income (OR = 1.57; 95% CI: 1.25-1.99), transportation barriers (OR = 3.39; 95% CI: 1.95-5.89), and family discouragement (OR = 3.03; 95% CI: 1.72-5.34) as significant predictors (all p < 0.001). Conclusions: A significant knowledge-practice gap persists across all 13 Saudi regions. These findings suggest several implications for a multi-level public health response to be evaluated through future intervention research; multi-level strategies targeting CHBMS Barriers are needed.
