Anti-tumor treatment is firstly considered for lung cancer, if secondary infection occurs, antibiotics can be used under the guidance of doctor, and cough suppressants can be used for severe cough. The main clinical manifestation of lung cancer is cough, usually paroxysmal irritating choking cough, no sputum or a small amount of foamy sputum. Lung cancer itself needs to be actively treated, with surgery as the main treatment and radiotherapy and targeted therapy as auxiliary. If the cough is caused by secondary infection, antibiotics, such as amoxicillin, are recommended. Anti-tumor treatment should be accompanied by symptomatic treatment. At present, according to the severity of cough of lung cancer patients, different cough suppressants are used. If the patient’s symptoms are relieved after severe coughing, it means that the tumor growth has caused the narrowing of bronchial tubes, and some cough suppressants, such as cough suppressants, can be considered. Lung cancer patients with symptoms of cough are recommended to go to regular hospitals for treatment.
