Materials and Methods: For 5000 women referred to BC clinic of Behbood hospital, a self-designed questionnaire including demographic-social characteristics and risk factors of BC was completed by researcher. Then breasts of women were examined by midwives and recorded in questionnaire. In case of abnormal results ultrasonography, mammography and fine needle aspiration (FNA) were prescribed and results were recorded in the questionnaire.

Results: A total 516 cases of left breast mass and 480 cases of right breast mass were palpated. Forty cases out of 996 ultrasonography were abnormal. A total of 183 cases out of 636 mammography were abnormal. One case out of 14 FNA was cancer (7.1%). Occupation, menopause status, history of performing FNA, education level, marriage status, age of first pregnancy and body mass index (BMI) had significant relationship with abnormal clinical breast examination (CBE). Breastfeeding had significant relationship with abnormal sonography results. Menopause, diet, use of chemical agents and type of oils used in diet had significant relationship with abnormal mammography results (P < 0.05).

Conclusion: Based on these results, women should be encouraged to undergo BC screening tests more regularly and to increase their knowledge on BC and benefits of screening through public media.
