As the main means of breast cancer screening, mammography has an accuracy rate of more than 90% in identifying and distinguishing benign and malignant breast tumors. Although most of the mammary calcifications observed on mammography are benign lesions, they also play an important role in the diagnosis of malignant tumors. According to statistics, about 80% of benign breast lesions and 20% of malignant tumors show calcification, while about 65% of breast cancer patients have breast calcification. In this study, we found that there were significant differences in the number, density, intensity, morphology and distribution characteristics of microcalcification in benign and malignant breast lesions. These differences provide an important imaging basis for the diagnosis of benign and malignant breast lesions. For example, microcalcifications in breast cancer tend to be low-density, large in number, and high in intensity, and are mainly fine sand-like, linear-branched, and worm-like, while benign lesions are mostly coarse-grained calcifications. In terms of distribution, the microcalcifications of breast cancer are mostly linear or segmental, while the benign lesions are mostly diffuse. Further studies also analyzed the mammography of patients with breast diseases, and found that the nature and manifestations of breast calcification have significant clinical significance for the differential diagnosis of benign and malignant breast lesions. In particular, in the early diagnosis of microscopic breast cancer and ductal invasive carcinoma, the classification and analysis of mammography calcification signs are particularly important. Therefore, it is of great significance to understand and grasp the classification and diagnostic value of mammography calcification signs to improve the diagnostic accuracy of benign and malignant breast tumors, promote early treatment, and improve the prognosis of patients.展开更多
