Symptoms to watch out for –
* Persistent difficulty in breathing, wheezing, chest pain or cough or blood in the sputum.
* Chest pain that worsens on taking a deep breath or travels from the shoulder to the arm.
If any of the above is present, especially with unexplained loss of weight or fatigue, it is time to see a doctor as soon as possible. Unfortunately, there are no symptoms in the majority of patients at an early stage and symptoms typically develop at a later stage.

There are no specific things you can look out for yourself, but your doctor may begin with a chest X-ray or CT scan, which may prove to be revealing.
