Introduction: Breast cancer is viewed as one of the most health-threatening among females. It has been considered the most extraordinarily fatal type of disorder. Worldwide, breast cancer is deemed the top reason for morbidity and mortality among females. This type of cancer is number one in many countries and is the second leading reason of death among females. Nevertheless, breast cancer can be faced via health education and proper screening, such as breast self-examination. The study aimed to investigate knowledge, practice, and barriers to breast self-examination among Omani women. Methods: This study will use a non-experimental, quantitative, cross-sectional design, with data collection at a single point. The study will be conducted in North Batinah Governorate in Oman. The target group will be women from different primary healthcare institutions. The Study's implication: There were few attempts to explore women's knowledge, practice, and barriers to breast self-examination. Therefore, this study is an endeavor to meet the current knowledge gaps in Oman regarding women's knowledge, practice, and barriers regarding breast self-examination. Studying women's knowledge and practice of breast self-examination will contribute to a better understanding of this screening test in Oman and how to promote it. This study is necessary to mothers, healthcare professionals, and policymakers by providing further knowledge of breast self-examination in Oman.
