Signs and Symptoms

It is difficult to detect lung cancer at an early stage. There are often no symptoms until the condition is well advanced. Examples of symptoms include:

  • Persistent cough
  • Persistent or recurrent lung infections (e.g., pneumonia, bronchitis)
  • Hoarseness
  • Shortness of breath
  • Wheezing
  • Chest pain
  • Fatigue or weakness
  • Weight loss
  • Loss of appetite
  • Coughing up blood

When lung cancer spreads (metastasizes) to other areas of the body, other signs and symptoms related to those sites may develop. Examples include bone pain, neurological symptoms, and swollen lymph nodes.
