Lung cancer
Evidence-based information to help you understand your condition.
Lung cancer develops when malignant cells form in the lungs. It can occur in people who have never smoked, though smoking is a major risk factor.
Early symptoms may include a persistent cough, chest pain, shortness of breath, or coughing up blood. However, early-stage lung cancer may not cause any symptoms.
If you have risk factors for lung cancer or are concerned about symptoms, specialist assessment including imaging may be recommended. Early detection can improve treatment outcomes.
