Choking cough of lung cancer may be caused by compression of recurrent laryngeal nerve or tracheo-esophageal fistula, which needs to be treated by surgery, radiotherapy and installation of stent. 1. Extrusion of recurrent laryngeal nerve: when lung cancer patients have metastasis in hilar lymph nodes, the tumor will extrude the recurrent laryngeal nerve, which will lead to choking cough and hoarseness of voice, etc. If the patients are able to undergo surgery, the first choice of treatment is surgical resection, which can be partial or complete; if the patients are not able to undergo surgery, radiotherapy and chemotherapy are considered to reduce the size of the tumor and alleviate the choking cough. 2. Tracheoesophageal fistula: Cancer cells invade the surrounding esophagus, and once the tumor tissue is necrotic, it will lead to tracheoesophageal fistula, and choking and coughing will occur when eating, in this case, it is necessary to install a stent through surgery to ensure the normal pathway of food, and at the same time, cooperate with the treatment of radiotherapy and chemotherapy. If choking cough occurs in lung cancer patients, they should consult the doctor in time to avoid aggravating their condition.
