Signs and symptoms of lung cancer

The symptoms of lung cancer may include:

  • a cough for three weeks or more
  • a change in a cough you have had for a long time
  • a chest infection that does not get better, or getting 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 three weeks or more.

Other possible symptoms are:

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

Lung cancer is occasionally diagnosed by chance when a person is having tests for another condition.

Sometimes, tiny cancer cells are left behind after cancer treatment. These can divide to form a new tumour.
