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
• wheezing
• a hoarse voice
• swelling of your face or neck
• persistent chest or shoulder pain
