Abstract
At present, mammography is the most accurate imaging method to detect breast calcification. Calcification can be found in benign and malignant breast lesions. Although its performance has different characteristics, it is still difficult to distinguish benign from malignant. The study of calcification in breast benign and malignant lesions is helpful to improve the imaging diagnosis of breast lesions, and provide a reference for the clinical treatment. In this paper, the significance of calcification in the diagnosis of benign and malignant breast lesions and the composition of calcified lesions were discussed. The classification, shape and distribution of BI-RADS in calcified lesions in breast benign and malignant lesions and their diagnostic significance were studied, and the pathological control was analyzed. The morphological and distribution of calcification in different subtypes of breast cancer was statistically significant. The distribution of calcification has some characteristics, which can be used as a basis for differential diagnosis. At present, the chemical composition of calcified lesions cannot be identified by X-ray, but we can use other methods to analyze the chemical composition of calcified lesions. Breast calcification can be divided into two types. The first type is calcium oxalate dihydrate, which appears in benign lesions. The second type is hydroxyapatite, which is found in proliferative lesions and mostly malignant. Although the appearance of mammography has optimized the imaging diagnostic methods of calcification, it still cannot provide information about the chemical composition of calcification, and cannot accurately define the nature of the tumor. In the latest study, Raman spectroscopy can be used to obtain information about the chemical composition of calcification, which can be used to differentiate benign and malignant calcification. This may be the direction of future diagnostic development.
