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.
