Background: Breast cancer is the most common cancer among women and the second most common all over the world. The survival rate of breast cancer also depends on the wide accessibility of society to medical services, so if the breast cancer is diagnosed in early stages, the survival rate will be ۸۰-۹۰% in ۵ years.Objectives: The objective of this research was to find the risk factors of breast cancer in Iranian women which put them in high risk group of breast cancer.Methods: Since September ۲۲nd, ۲۰۲۰ till March ۲۰th, ۲۰۲۱, ۳۰۰ women who had been referred for mammography service in Imam Khomeini Hospital. All patients were asked to fill the questionnaires which was included the possible risk factors of breast cancer, then in first step a standard two-view mammography were acquired. All mammograms were interoperated by radiologists and were scored based on BIRADS (breast imaging and reporting data system). Based on BIRADS we categorized patients into high and low risk groups of breast cancer. To state any relationship between these two groups with possible risk factors we run Chi-Square test.Results: Among all ۱۶ risk factors only ۱- age, ۲- marital status, ۳- menopause status and ۴- mass palpation had a significant relationship with BIRADS. Single women, Women with age of ۳۰-۳۹, women who experienced menopause in an age interval of ۴۵-۵۵ and the ones with mass palpation were more likely to be in high risk group of breast cancer.Conclusion: Based on the related risk factors, medical service providers could prioritize women with high risk of breast cancer to have access to medical services. The sooner they will be diagnosed the survival rate of breast cancer will be increased.
