Lung adenocarcinoma patients with symptoms of cough after surgery have no specific recovery time, according to how long the cough is related to the cause of cough. Due to tracheal intubation during surgery, lung adenocarcinoma patients often have cough symptoms after surgery, and the cough may get better after several weeks after surgery if it is caused by this reason. If the cough is caused by lung infection after surgery, the cough may disappear after the infection improves due to active anti-infection treatment. Cough due to incomplete resection of lung adenocarcinoma tumor or recurrence of tumor within a short time after surgery may need specialized oncology treatment to reduce the size of the lesion before the cough symptom can get better gradually. If the cough symptoms are serious and do not show signs of improvement, patients should go to the hospital in time to avoid delaying their condition.
