Methods: Analyzed the mammographic images of 118 patients with breast cancer confirmed by surgery and pathology. Among 118 cases, 70 cases were infiltrating ductal carcinoma (59.3%), 17 cases were ductal carcinoma in situ (DCIS, 14.4%), 7 cases were mucinous carcinoma (5.9%), 5 cases were medullary carcinoma (4.2%), 1 case was tiny micro carcinoma (0.9%) and 18 cases were other types cancer (15.3%). Results: The mammographic appearance of 118 patients with different breast cancer included: tumor mass (n = 80, 68.8%), microcalcification (n = 57, 48.3%), which were subdivided into two groups (a) microcalcification only, 13 cases (13/118, 11%); (b) combined with other mammographic features: 31 cases with tumor mass (31/118, 26.3%); 7 cases with architecture distortion (7/118, 5.9%), 6 cases with focal asymmetric density (6/118, 5.1%). Six cases appeared as architecture distortion only, 41 cases with abnormal vessel signs (34.7%). Conclusion: The microcalcifications are the most frequently basal X-ray signs in DCIS. Architecture distortion and focal asymmetric density are special X-ray signs that were easily missed. The abnormal vessels are also important accompaniment signs of breast cancer. The use of coned compression technique is particularly important to improve the radiological diagnosis of breast cancer.展开更多
