Non-small cell lung cancer: It is a disease in which cancer cells form in the tissues of the lungs. The major risk factor for non-small cell lung cancer is smoking. Symptoms include a cough that does not go away and shortness of breath.

Malignant pleural mesothelioma: It is a type of cancer that develops in the mesothelium (a lining that covers the outer surface of organs), predominantly caused by exposure to asbestos. Symptoms of mesothelioma in the lining of the lungs include chest pain, shortness of breath, extreme tiredness, persistent cough, loss of appetite, unexplained weight loss, fever and sweating, particularly at night.
