There are usually no signs or symptoms in the early stages. Symptoms of lung cancer develop as the condition progresses.
The main symptoms of lung cancer include:
- a cough that doesn’t go away after 2 or 3 weeks
- a long-standing cough that gets worse
- chest infections that keep coming back
- coughing up blood
- an ache or pain when breathing or coughing
- persistent breathlessness
- persistent tiredness or lack of energy
- loss of appetite or unexplained weight loss
If you have any of these, you should see a GP.
Less common symptoms of lung cancer include:
- changes in the appearance of your fingers, such as becoming more curved or their ends becoming larger (this is known as finger clubbing)
- difficulty swallowing (dysphagia) or pain when swallowing
- a hoarse voice
- swelling of your face or neck
- persistent chest or shoulder pain
