Breast cancer is the most common type of cancer among women. Reasons such as diagnosing breast cancer at an early stage increases the chances of treatment and survival, and the fact that the masses are largely noticed by the individual themselves, point to the importance of breast self-examination (BSE) . BSE skill is among the nursing skills. When the literature was examined, it was seen that the web-based education method was frequently used for cognitive skills during nursing education, but its use was limited for psychomotor skills training. It was determined that in BSE training, in addition to traditional education, methods such as concept maps and peer-supported education were used, but web-based education methods were not used. It is thought that the study will contribute to the literature in these aspects.

Due to the recent pandemic, nursing education, like other universities, was conducted web-based. Skills training in nursing, which is an applied education, has also been tried to be provided on a web-based basis. It is stated that the positive attitude towards e-learning increases the quality of education and student success. Additionally, with e-learning, the learner assumes individual learning responsibility. On the other hand, lack of motivation, attention, communication and interaction are the disadvantages of e-learning . Breast cancer is the most common type of cancer among women.
