6mm pure ground glass nodules are mostly caused by benign lung diseases and are mostly not serious, but there is some risk of malignant tumors such as lung cancer, which is more serious.
The malignancy rate of pure ground glass nodules in the lungs is high, about 18%, while the malignancy rate of lung nodules of 6mm size is about 1%. Therefore the malignancy rate of 6mm pure ground glass nodule is not high.
If it is caused by pneumonia with viral or bacterial infection, it can usually be improved or cured by taking antibiotic treatment such as ceftriaxone. If the nodule is a focal carbon deposition or focal fibrosis, it can be followed up and observed, or the symptoms can be relieved by using sputum-cleansing drugs such as aminoglutethimide.
If it is atypical adenomatous hyperplasia, carcinoma in situ and other pre-invasive lesions, it is not a malignant tumor, but it has a certain malignant rate, and it is a pre-cancerous lesion, which is not serious at the moment, but it needs to be closely followed up and observed.
If it is a malignant tumor such as lung cancer, it is more serious and the prognosis is poorer and may be life-threatening if not treated in time. However, since the 6mm lesion is small, it mostly belongs to the early stage of lung cancer, and active treatment can improve the prognosis.
Patients are advised to consult their doctors for a comprehensive analysis of the possible causes of the disease based on the shape of the lesion, calcification, etc., and follow the doctor’s instructions for further examination and treatment.
