Unfortunately, lung cancer usually doesn't cause symptoms until the cancer has advanced. When symptoms do appear, they may include:

  • Persistent cough that worsens
  • Constant chest pain
  • Problems breathing, wheezing
  • Coughing up blood
  • Feeling very tired all the time
  • Unintended weight loss or loss of appetite
  • Repeated pneumonia or bronchitis
  • Neck or facial swelling

These symptoms can occur with other, less-serious diseases as well. If you're experiencing any of these, talk with your physician. If it is cancer, the earlier you get a diagnosis, the better.
