The discovery of calcified spots on mammogram does not determine the specific nature of the tumor. Malignant calcification foci are mainly manifested as aggregated, small, multilinear, rough, uneven and irregularly shaped calcification foci, which also need to be judged according to its shape density and distribution shape. It is also necessary to make further judgments based on the shape and nature of the lump, and if necessary, further puncture examinations or surgical removal of the lump should be performed and sent for examination. Mammography is still an important tool for the early detection of breast cancer. Mammography calcification alone cannot confirm the type of disease.
