If a breast cancer is malignant, radical surgery should be performed and chemotherapy, radiotherapy and endocrine therapy should be selected according to the pathological results. Because about 30%-50% of patients with breast cancer, malignant tumors are accompanied by microcalcifications in the breast. Patients with calcifications in the breast tissue are 47 times more likely to have breast cancer than those without calcifications. Clinically, tiny, granular, clustered microcalcifications may be an early sign of breast cancer. In fact, early breast calcification can be detected and its nature determined by mammography, and in early screening, early detection and treatment are possible, which can improve the survival of breast cancer patients. Women should never take lightly the insidious breast calcifications that are found to be inaccessible but growing silently during the examination, they must insist on review and preferably undergo surgery in time.
