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.
