Comparative Accuracy of Mammography and Ultrasound in Women with Breast Symptoms According to Age and Breast Density

摘要

Breast cancer is the most common cancer and the second most common cause of death from cancer in women.Th e aim of this studywas to determine which is more accurate imaging test mammography or ultrasound for diagnosis of breast cancer based on the women’s age and breast density. We examined ... patients with breast symptoms, by clinical breast examination, mammography and ultrasound. A total of ... breast lesions were examined by histopathology analyses. Histopathology results revealed the presence of ... invasive cancers, and ... benign lesions. Sensitivity varied signifi cantly with age and breast density. In the ... women who had both tests, ultrasound had a higher sensitivity than mammography in women younger than .. years, whereas mammography had a higher sensitivity than ultrasound in women older than .. years. Th e sensitivity according to age was ..,.. for mammography and ..,.. for ultrasound. Th e specifi city according to age was .., .. for ultrasound and .., .. for mammography. Comparing the sensitivity of mammography and ultrasound according to the breast density indicates that mammographic sensitivity was ..,.. among women with predominantly fatty breast, but ..... in women with heterogeneous dense breasts, with the increase of fi bro glandular density the level of sensitivity with mammography decreases, while ultrasonographic sensitivity was ..,.. among women with predominantly fatty breast and ..,.. for heterogeneous dense breasts. Our data indicate that sensitivity and specifi city of ultrasound was statistically signifi cantly greater than mammography in patients with breast symptoms for the detection of breast cancer and benign lesions particularly in dense breast and in young women.n
