Abstract:
Objective To investigate the diagnostic significance of microcalcifications in breast cancer.Methods 120 cases of breast lesions with microcalcifications confirmed by pathology were included in this study,of them,97 cases were breast carcinoma,including infiltrating ductal carcinoma(n=71),invasive lobular carcinoma(n=23),and others 3 cases,23 cases were benign breast diseases.All cases underwent mammography,X-ray features of microcalcification were analysed in comparison with that of pathology.Results (1)The microcalcifications of breast in totally 120 cases could be divided into 3 types according to the density of calcifications,those were high (45/120),middle (34/120) and low (41/120) density.The middle and low dense microcalcifications were more seen in breast cancer(73.19%,71/97),high dense microcalcifications were more seen in benign breast diseases(82.00%,19/23).(2)The malignant calcifications were mostly less than 0.5 mm in diameter.The calcifications appeared as sandy in 68/97,bulky in 18,“Y”,“V”,branch or club in 8 and worm in 3.The benign calcifications were mostly more than 0.5 mm in diameter with regular form and defined margin.(3)Dense or clustered microcalcifications were often seen in breast cancer (82/97),scatter and/or bulky microcalcifications were more seen in benign breast diseases(16/23).Conclusion Microcalcification is important finding in diagnosis of breast cancer,espcially early cancer on macrography,but it should differentiate with benign breast microcalcifications.
