Smoking is generally not recommended for lung nodules, which may lead to exacerbation of the disease, and it is also not recommended for normal people. Lung nodules may be caused by local inflammation and infection, or by malignant tumors such as bronchopulmonary cancer or lung cell lung cancer. No matter which disease causes lung nodules, smoking is not recommended. Cigarettes are irritating, and benign nodules may become malignant after being constantly stimulated. In the case of malignant lesions, continued smoking may lead to increased congestion and edema of the lung mucosa, and in severe cases may lead to the exudation of a large amount of inflammatory substances, which will make the pathological changes more pronounced, and therefore it is not recommended that patients with lung nodules smoke. Smoking is also not recommended for normal people, as cigarettes contain nicotine, which is harmful to health. If the cause of the lung nodules has not yet been identified, it is recommended that the patient continue to cooperate with the doctor for further examination.
