Calcification on the lungs. What does that mean?

Pulmonary calcification is the lung inflammatory reaction after treatment left a higher density shadow, these inflammatory reactions are pneumonia or tuberculosis, if the lung has calcification points prove that the disease has been completely recovered, and there is calcification points prove that the disease has been before, that is all, and there is no harm. The normal occurrence of pulmonary calcification is caused by tuberculosis, but prolonged cough may also cause inflammation and pulmonary calcification, but the possibility of tumor is relatively small. Pulmonary calcification is mainly one of the forms of tuberculosis recovery. Normal lung tissue is composed of alveoli, lymphocyte microtubules, bronchioles, etc., and is pink. If a considerable number of highly toxic tuberculosis bacteria invade lung tissue, grow and reproduce in it, and produce metabolites, lung tissue will be destroyed, showing substances like spoiled milk and dried cheese, which will make normal physiological structure and function disappear. Medically, it is called caseous necrosis, and we call it calcification of lung. Calcification in the lungs. That's it.
