Early-stage lung cancer may not cause any noticeable symptoms.

Common symptoms of lung cancer at a more advanced stage include:

• Persistent cough that gets worse over time
• Shortness of breath
• Blood in the sputum
• Constant chest pain (may occur in association with a chronic cough)
• Recurrent chest infection and fever
• Weight loss

When to see a doctor

Make an appointment with your doctor if you have any signs or symptoms that worry you.
