Abstract: Breast cancer is the second most common cause of death from cancer in women. The aim of this study was to determine which is more accurate imaging test mammography or ultrasound for diagnosis of breast cancer based on the womens age and breast density. We examined 40 patients with breast symptoms, by clinical breast examination, mammography and ultrasound. A total of 40 breast lesions were examined by histopathology analyses. Sensitivity varied significantly with age and breast density. In the 20 women who had both tests, ultrasound had a higher sensitivity than mammography in women younger than 50 years, whereas mammography had a higher sensitivity than ultrasound in women older than 50 years. The sensitivity according to age was 12.5 % for mammography and 17.5 % for ultrasound. Comparing the sensitivity of mammography and ultrasound according to the breast density indicates that mammographic sensitivity was 20 % among women with predominantly fatty breast, but 5 % in women with heterogeneous dense breasts, with the increase of fibro glandular density the level of sensitivity with mammography decreases, while ultrasonography sensitivity was 5 % among women with predominantly fatty breast and 30 % for heterogeneous dense breasts
