Shortness of breath—also called dyspnea—is the feeling that you cannot get enough air or catch your breath. It can have many possible causes, including heart and lung conditions such as lung cancer.
Lung cancer may interfere with breathing when a tumor narrows an airway, fluid builds up around the lungs, or the disease affects healthy lung tissue. New, persistent, or worsening shortness of breath should be discussed with a healthcare provider. Sudden or severe breathing difficulty may require immediate medical attention.
