RESUMO
Introduction Breast cancer is the leading type of cancer in women globally, contributing significantly to cancer-related deaths. In Saudi Arabia, it ranks as the second most common cancer among women. Studies have highlighted a lack of awareness about breast cancer, negatively impacting breast self-examination practices. The Eastern Province has particularly high incidence rates. Knowledge of risk and protective factors can aid in prevention and early detection. While some studies show good awareness, this research aims to assess women's knowledge and attitudes about breast cancer risk factors and warning signs in the Eastern Province. Methodology This is a cross-sectional study conducted in Saudi Arabia's Eastern Province from June to October 2023 to assess breast cancer awareness among adult females. Data were collected via an online survey. Data were cleaned in MS Excel (Microsoft Corporation, Redmond, Washington) and analyzed in IBM SPSS Statistics for Windows, Version 23 (Released 2015; IBM Corp., Armonk, New York). Results Our study assessed breast cancer awareness in 697 participants in Saudi Arabia's Eastern Province. Most were aged 20-24 years (30.3%), married (49.2%), and Saudi nationals (97.6%), with higher education (59.4%). Significantly, 69.2% received education on breast cancer risk factors/signs. Some had personal breast cancer diagnoses (5.0%), and 31.7% had affected family members. Participants showed good awareness of various risk factors and warning signs. Significant associations were found between nationality, personal breast cancer diagnosis, and knowledge and attitudes about risk factors. Age, marital status, occupation, education on breast cancer, and personal breast cancer diagnosis influenced knowledge and attitudes about warning signs. Conclusion Our study findings indicate generally good awareness of breast cancer risk factors and warning signs among participants. Age, marital status, occupation, education on breast cancer, and personal breast cancer diagnosis influenced knowledge and attitudes about risk factors and warning signs. Educational efforts should target lesser-known risk factors to enhance prevention and early detection.
