Small nodules on the lungs usually do not require treatment if they are benign lesions, while inflammatory and malignant lesions require treatment. Lung nodules are small, rounded shadows with increased density on imaging, which may be benign lesions such as inflammatory granulomas or fibromas, and need to be reviewed regularly; if they do not increase in size, they do not require treatment. If the nodule is caused by lung infection, most of the nodules can disappear after systematic anti-infection treatment. If the nodule has malignant signs such as burrs and vascular clusters, it is considered to be malignant, and pathological biopsy is needed if necessary, and if the nodule is diagnosed to be early stage lung cancer, it needs to be aggressively operated. Whether small nodules on the lungs need to be treated or not can not be generalized, and it should be decided according to the specific situation of the patient, who needs to consult a doctor in time and follow the professional guidance of the doctor.
