Detection Of Small Breast Cancer By Mammography And Ultrasonography In The 146 Cases

To improve the early diagnosis of breast cancer through a study of the mammography and ultrasonography finding of the first stage breast cancer. Methods: The mammography and ultrasonography findings of 146 cases of the first stage breast cancer (Φ≤2.0 cm) were studied and compared with pathological results. Results: The diagnostic accuracy of ultrasonography and mammography was no statistical difference respectively(p=0.716) when 40 cases intramamary diameter were in 1cm. However, In detecting breast fine cluster of calcification, the sensitivity of mammo- graphy was better than ultrasonography. There was a statistical difference between both modalities (p=0.013), ultrasonography was surperior to mammography between lcm to 2cm. Conclusion: The patient suspect-ed of small breast cancer should combined the mammography with ultrasonography to improve the diagnostic rate of the first stage breast cancer.
