The low adherence of women of reproductive age in performing BSE indicates the need for targeted health education Purpose: To knowing knowledge and attitudes as determinants of women's compliance in carrying out breast self-examination. Method: A quantitative quasi-experimental design with a one-group pre-test post-test approach involving 67 women of reproductive age in Gonilan Village. The intervention was delivered through face-to-face counseling. The Wilcoxon test was used to assess the effect of the intervention, while the Chi-Square and Fisher Exact tests were used to examine variable relationships. Results: There was a significant increase in knowledge, attitude, and adherence scores after the intervention (p = 0.003). A significant association was also found between knowledge and adherence (p = 0.028) as well as between attitude and adherence (p = 0.043). Conclusion: Breast self-examination education is effective in improving early breast cancer detection behavior. Keywords: Attitude; Breast Self-Examination; Compliance; Knowledge; Women.
