Micro nodules in the upper lobe of the left lung and the lower lobe of the right lung are categorized into drug treatment and surgical treatment according to the causes of the disease. 1. Medication: If the nodule is inflammatory, oral antibiotics such as moxifloxacin should be taken as prescribed by the doctor; if the nodule is tuberculous, oral anti-tuberculosis drugs such as rifampicin should be taken; if the nodule is fungal infection, oral anti-fungal drugs such as voriconazole should be taken as prescribed by the doctor. 2. Surgery: If the nodule is considered to be malignant, further evaluation is needed for surgical treatment, including lung wedge resection, segmental resection, lobectomy, etc., and the need for postoperative chemotherapy and radiotherapy will be determined according to the specific pathologic results. If you are suffering from lung micronodules, it is recommended that you seek medical attention in a timely manner, and depending on the shape, size, and changes of the nodules, your physician will conduct an evaluation and decide on the next treatment plan.
