What does lung nodule mean, is it serious?

Pulmonary nodules generally refer to pulmonary nodules. Pulmonary nodules are solid or subsolid lung shadows. Whether they are serious or not needs to be judged according to specific conditions.

Pulmonary nodules belong to an imaging description. The clinical manifestations are focal, quasi-circular and dense solid or subsolid lung shadows with a diameter of ≤3cm. Generally, they are the result of mutual competition between immune cells and humoral immune function of the body. According to the benign and malignant condition, lung nodules can be divided into benign nodules and malignant nodules, among which benign nodules include pulmonary tuberculoma, pulmonary aspergillosis, pulmonary fibroma, etc. After anti-infection treatment or surgical resection, clinical cure can generally be achieved, usually not serious. However, if pathologically confirmed as malignant nodules, such as lung cancer, clinical symptoms such as cough, hemoptysis, chest distress, dyspnea, etc., generally more serious.
