How to treat something inside the lungs depends largely on the nature of that something. The more common is the inflammatory reaction caused by inflammatory nodules, if it is a bacterial infection, you can choose antibiotics, such as cefuroxime, cefradine, levofloxacin, roxithromycin, clindamycin and other drugs. If the nodules are due to Mycobacterium tuberculosis infection, then anti-tuberculosis drugs, such as isoniazid, rifampicin, ethambutol, pyrazinamide, etc., should be used in combination at an early stage. In addition, if it is a teratoma or a misshapen tumor, then if it compresses the lung tissue and the symptoms of dyspnea appear, it should be possible to relieve the symptoms through surgical resection. If it is malignant, such as bronchopulmonary cancer, it should be surgically removed early and supplemented with radiotherapy and chemotherapy and given targeted drug therapy.
