The value of the combination of mammography and ultrasonography in detection of the 146 cases with stage I breast cancer

Objective: To improve the early diagnosis of breast cancer through a study of the mammography and ultrasonography finding of the stage Ⅰ breast cancer.Methods: The mammography and ultrasonography findings of 146 cases of the stage Ⅰ breast cancer(ф≤2.0 cm) were studied and compared with pathological results.Results: The diagnostic accuracy of ultrasonography and mammography was no statistical difference respectively(P0.05).When 40 cases intramamary diameter were in 1 cm.When assessing the lession arising in atrophy type breast.However,In detecting breast fine cluster of calcification,the sensitivity of mammography was better than that of ultrasonography.There was a statistical difference between both modalities(P0.05),ultrasonography was surperior to mammography between 1 cm to 2 cm.Conclusions: The patient suspected of small breast cancer should combined the mammography with ultrasonography to improve the diagnostic rate of the stage Ⅰ breast cancer.
