Lung cancer often causes no symptoms in its early stages, which is why it is frequently diagnosed late. Being aware of warning signs — especially if you smoke or have smoked — can help with earlier evaluation.
Symptoms to watch for
- A new cough that persists, or a change in a long-standing cough
- Coughing up blood
- Chest pain that worsens with deep breathing or coughing
- Unexplained weight loss or loss of appetite
- Persistent breathlessness or hoarseness
- Recurrent chest infections
What to do
These symptoms are more often caused by other conditions, but they should be assessed. Evaluation may include a CT scan and, when needed, bronchoscopy or EBUS-TBNA to obtain tissue for diagnosis.
