Lung cancer typically doesn't cause signs and symptoms in its earliest stages. Signs and symptoms of lung cancer typically occur only when the disease is advanced.

Signs and symptoms of lung cancer may include:

  • A new cough that doesn't go away
  • Changes in a chronic cough or "smoker's cough"
  • Coughing up blood, even a small amount
  • Shortness of breath
  • Chest pain
  • Wheezing
  • Hoarseness
  • Losing weight without trying
  • Bone pain
  • Headache

When to see a doctor

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

If you smoke and have been unable to quit, make an appointment with your doctor. Your doctor can recommend strategies for quitting smoking, such as counseling, medications and nicotine replacement products.
