Background: This research evaluated the effectiveness of an online education model in teaching breast selfexaminationto university staff and students. Materials and Methods: 1,679 women participated in a breastself-examination online training program. Breast self-examination knowledge evaluation forms developed byMaurer (1997) were used in the research and were evaluated on a 100 point scale. Paired t-test and McNemar’sTest statistics were employed. Results: The participants scored an average of 46.5 (14.0%) on knowledge onbreast self-examination before training, but 77.4 (11.0%) one month after education and 76.7 (9.52%) after sixmonths. There was a clear significant difference between these knowledge levels (p<0.05). Similarly, while therate for systematic practice of breast self-examination among women was 30.8% before training it increased to47.8% afterwards. Again the difference was significant (p<0.05). Conclusions: Online education is an effectivemethod for teaching breast self-examination to women.
