Abstract: Breast cancer is the most common form of cancer affecting women at any age. The purpose of this study was to describe breast cancer detection practices among women in Tabriz, Iran. This study was a descriptive research. Study participants were 109 women aged 17-53. A questionnaire was used to elicit information related to their practices. Findings revealed that 46.8% of women had breast cancer detection practices and 53.2% of them had no practical experience in this regard. Screening methods in women who had performed breast cancer detection included: BSE 70.4%, Clinical breast examination 21.3% and BSE+Clinical breast examination 8.2%. Nobody had performed Mamography, Ultrasound and breast biopsy. The reasons of women who had not performed screening methods were concern about abnormal signs in breast, believe to non preventable of breast cancer, poor knowledge and lack of problem and disease. The findings showed that the women`s practice in terms of breast cancer detection is not satisfactory, therefore to encourage women to use screening methods regularly, the health authorities should pay the attention to breast cancer detection in the national educational programs and strategies.
