Lung Cancer: 10 Things to Know
Man with chest pain

2. There are often no symptoms in the early stages.

Tumors can grow in the lungs without causing pain or discomfort. As a result, lung cancer typically doesn’t cause symptoms in the early stages. By the time most people notice symptoms, lung cancer usually has become advanced and spread to other parts of the body. When symptoms develop, they may include hoarseness, shortness of breath, and chest pain that worsens with deep breathing, coughing, or laughing. A cough is also common—a new cough that doesn’t go away or worsens over time, or changes in a chronic cough. The cough may produce blood or bloody or rust-colored mucus.
