Dry cough caused by lung cancer may be alleviated with appropriate medication for some patients in clinical settings. However, a dry cough caused by lung cancer is often due to the size and location of the tumor. If the tumor is not effectively removed, patients may experience chronic symptoms such as dry cough. Therefore, even after surgery, the symptom of dry cough may persist for those with lung cancer. For cases like early-stage lung cancer, if the tumor is removed early, some patients may see significant improvement in their dry cough. However, for those with advanced-stage lung cancer, dry cough may continue even after the tumor tissue has been removed, making dry cough caused by lung cancer generally difficult to cure in clinical practice.
