Typically, lung cancer does not have symptoms in its earliest stages — when it’s most treatable. But as the cancer grows, symptoms may become more noticeable.
Common symptoms include:
- A cough that gets worse or does not go away
- Trouble breathing, such as shortness of breath
- Constant chest pain
- Coughing up blood
- A hoarse voice
- Frequent lung infections, such as pneumonia
- Constantly feeling exhausted
- Unexplained weight loss
Most often, other health issues cause these symptoms, not cancer. However, people who experience these symptoms should see a doctor as soon as possible.
