Symptoms
Early lung cancer often does not cause symptoms. But as the cancer grows, common symptoms may include:
- a cough that gets worse or does not go away
- breathing trouble, such as shortness of breath
- constant chest pain
- coughing up blood
- a hoarse voice
- frequent lung infections, such as pneumonia
- feeling very tired all the time
- weight loss with no known cause
Most often these symptoms are not due to cancer. Other health problems can cause some of these symptoms. Anyone with such symptoms should see a doctor to be diagnosed and treated as early as possible.
