Calcification of the lungs does not present particularly obvious symptoms, such as coughing and sputum, which are common in lung diseases. Because calcification is mainly reflected in the lymph nodes, lymph nodes with inflammation and viruses will gradually disappear in the process of fighting, such as inflammatory reaction around the lymphatic follicles, and finally lead to calcification of the lymph nodes in the lungs, after calcification of the lymph nodes will also lose the function of resistance to inflammation and viruses, through the X-ray will find that the density of lymph nodes in the lungs will be increased, and appear to have the shape of the larger, surrounded by the phenomenon of roughness. A common disease that causes calcification of the lungs is tuberculosis. Both unabsorbed tuberculosis foci and tuberculosis-induced calcification of lymph nodes belong to the cellular immune response, so the process of calcification may cause fever and weakness.
