Abstract

Introduction & Objective: Total rate of mortality due to breast cancer has been remained almost constant in contrast of increasing rate of breast cancer incidence. This shows improvement in early diagnosis of this disease. After clinical examination, mammography and sonography are the best early diagnostic methods of breast cancer. The aim of this study was to compare sonography results and findings of clinical examinations and mammography. Materials & Methods: In this study, all women engaging in Markazi province university of medical sciences were underwent breast clinical examination in this study and mammography, sonography and needle or tissue biopsy were accomplished for them if there was any indications. Collected data were analyzed by EPI test in SPSS software. Results: The number of 979 cases with age rang of 20 to 45 years old were examined. The incidence of breast cancer was obtained 0.03%. Sensitivity and specificity indexes of sonography with 95% confidence interval as compared with clinical examination were reported 25.8% and 71.9%, and as compared with mammography were reported 5.0% and 7.1%. Conclusions: Sonography in breast lesions, with higher possibility of being found in clinical examinations, is a better diagnostic method than lesions with more specificity of mammography. So, mammography could not been replaced by sonography, although sonography is more acceptable for patients.
