What's with the pulmonary nodules?

In the case of pulmonary nodules, the first consideration is that the air pollution is too heavy, which causes the lungs to inhale too much particulate matter, thus forming pulmonary nodules. Secondly, consider that lung inflammation such as pneumonia, tuberculosis and other diseases will lead to pulmonary nodules. Furthermore, considering the infiltrative tumor in the lung, which leads to ground glass nodules in the lung, we need to go to the hospital.

Nip in the bud means that we should take some preventive measures before lung cancer occurs. We call this measure primary prevention. What are they? The first is to ban smoking and not to smoke second-hand smoke; The second category is to minimize the inhalation of polluted air and protect the environment; The third category is occupational prevention, wearing masks to avoid some occupational hazards; The fourth category is scientific diet, eating more fruits and vegetables to prevent lung cancer.
