Signs and symptoms of lung cancer

Symptoms of lung cancer include a cough, repeated chest infections, breathlessness, unexplained pain, weight loss or tiredness.

Lung cancer may not always have symptoms early on. Sometimes it is found by chance when a person is having tests for another condition.

The symptoms of lung cancer can include:

  • a cough for 3 weeks or more
  • a change in a cough you have had for a long time
  • a chest infection that does not get better, or repeated chest infections
  • feeling breathless and wheezy for no reason
  • coughing up blood
  • chest or shoulder pain that does not get better
  • a hoarse voice for 3 weeks or more.

Other possible symptoms are:

  • loss of appetite
  • losing weight for no obvious reason
  • feeling tired.

If you have any of these symptoms, it is important to get them checked by your GP.

Many of these symptoms can be caused by other lung conditions or by smoking.
