A cough is usually a valuable resource that helps eliminate germs or harmful elements from airways. However, sometimes, the cough is not linked to a cold or an infection and may persist for weeks or months as is often the case in patients with lung cancer.

A chronic cough is the most characteristic symptom of patients with lung cancer and is caused by the irritation generated by the tumor in the bronchi and bronchioles. In those patients, usually, smokers who already had a cough as a result of respiratory problems, there is an increase or exacerbation of this symptom.
