If it is caused by a benign disease, the lung ground glass nodules can be cured through, if it is a malignant disease is usually difficult to completely cure. Common diseases include pneumonia, tuberculosis, lung cancer and so on. 1. Pneumonia: when the lungs are infected, it will lead to alveolar exudation, which in turn will show ground glass-like lesions in CT examination. In this case, anti-infection treatment against the causative agent according to the doctor’s prescription is usually enough to achieve a curable effect. 2. Tuberculosis: After being infected with Mycobacterium tuberculosis, it is easy to cause harm to the lungs and show ground-glass nodules in the lungs. Generally speaking, as long as you follow the doctor’s instructions to take anti-tuberculosis drugs in a timely manner, you can achieve a good prognosis. Common drugs include isoniazid, rifampicin, ethambutol and so on. 3. Lung cancer: besides benign diseases, some patients with ground-glass nodules belong to early lung cancer or precancerous lesions. If malignant nodules are confirmed by puncture biopsy or highly suspected to be malignant, surgery should be performed as early as possible for resection. After surgery, depending on the specific condition, radiotherapy, chemotherapy, targeted therapy, etc. may be required, but recurrence is still possible. Many lung diseases can lead to pulmonary ground glass nodules. Therefore, to determine whether it is curable or not, one should determine the cause of the disease through examination and understand the severity of the disease.
