Background: Early detection of breast cancer is of great importance to improve women’s health and to decreasethe cost related to cancer death. Therefore, recognition of variables related to breast cancer screening behaviorsis necessary. Objectives of this study were to identify the rates of breast self-examination (BSE) performance andmammography use in Iranian women, and to characterize the demographic and cognitive factors associated withtheir breast cancer screening behavior. Method: Data were collected from a convenience sample of 388 females,using an adapted version of Champion’s revised Health Belief Model Scale. Results: The results showed that7.5% of the participants performed BSE on a regular monthly basis, and among the women aged 40 and older,14.3% reported having had at least one mammography in their lifetime. Perceived self-efficacy and perceivedbarriers to BSE were significant predictors for BSE performance. For having mammography, health motivationwas the main predictor. Conclusion: Eliminating barriers and increasing perceived self-efficacy with an emphasisto make the women acquainted with BSE performance; as well as increasing health motivation of women andpersuading of physicians for clinical breast examination (CBE) performance with low cost and free access tom ammography, are important to promote BSE and mammography.
