Calcifications are not cancerous. However, some malignant tumors are characterized by sand-like calcification, such as breast cancer. Calcification refers to the process of necrosis of certain tissues in the body under the action of some factors, followed by the deposition of calcium salts in the necrotic foci in the body, which confines and stabilizes the lesions. Calcification is the body’s defense response to the lesion, which facilitates the clearance of the necrotic foci and the reduction of inflammation. The presence of calcification in tissues other than bone and teeth in the human body suggests the possibility of previous localized disease, such as calcification of lung tissue remaining after healing from tuberculosis, or calcification of inflammatory prostate infections after treatment. Sandy calcification is formed after subtle necrosis of local tissues. In contrast, carcinoma is the result of long-term exposure of normal cells to stimuli such as chemical substances or radioactive substances, which causes mutations in genes, changes in cell morphology, and unlimited cell proliferation. If calcified lesions appear and patients are not sure about this, they can have regular checkups to observe whether there are changes in calcification. At the same time, the patient should usually divert attention appropriately, can go out for a walk, take a walk, pay attention to the regularity of work and rest, diet and nutrition.
