Patients with advanced lung cancer with pulmonary exudation can be treated by drugs, chemotherapy and thoracocentesis as prescribed by doctors. 1. Drugs: For lung exudation caused by advanced lung cancer, diuretics can be used as prescribed by doctor, such as amphotericin tablets, spironolactone tablets, etc. Meanwhile, if lung exudation is caused by infection, it needs to be treated with antibiotics. 2. Chemotherapy: if the amount of pulmonary exudation in advanced lung cancer is small, chemotherapeutic drugs such as cisplatin can be directly injected into the pleural cavity to stimulate the adhesion between the dirty layer and the wall layer of pleura and close the pleural cavity, which can inhibit the production of effusion. 3. Thoracic puncture: if the amount of exudation from lungs in advanced stage of lung cancer is relatively large, it will compress the lungs and affect the respiratory function. In order to alleviate the condition, pleural puncture and drainage can be used to drain out excessive pleural fluid and alleviate the patient’s symptoms. It is recommended that patients with advanced lung cancer oozing from lungs should seek medical treatment in time and under the guidance of doctors to avoid delaying the condition and causing adverse consequences.
