The severe cough of lung cancer does not mean short survival time, so the patient should adjust his mind and go to the hospital in time to receive regular treatment. Lung cancer is a malignant tumor occurring in the lungs, and the survival period of lung cancer patients is generally related to the type of disease, stage and treatment of patients, etc. Violent cough does not mean the condition is serious, and it is not a manifestation that the patient will not live for a long time. The probability of lung cancer patients coughing is very high. Generally, early, middle and advanced lung cancer patients will have coughing symptoms, which may be related to lung irritation, tumor compression, pneumonia, infection, etc. Patients should go to the hospital in time to receive examination and symptomatic treatment. If a patient is in early or middle stage of lung cancer, even if he/she has a severe cough, the survival period is still very long after active treatment. For advanced lung cancer patients, they should also keep a positive mindset and cooperate with doctors for active treatment, which can effectively prolong the survival time and improve the quality of life.
