In this research 600 staff of an educational office (distric seven) were being studied before and after they were educated about breast self-examination. Necessary information was gathered before and after they were educated through questionnaires. The result of the study showed that the average scores of their awareness before and after they were educated was 42.3 and 44.2, respectively. Hence, there was a significant difference because of the education of self-examination women's breasts (P<0.0001). There was no difference between family members nor between those who had different marital status, concerning the awareness of breast self-examination. However, there was a large difference between the educational level of women who were studied and the educational level of their spouses, according to their knowledge concerned about monthly breast self-examination (P=0.04).
