What are some of the first symptoms of lung cancer?

No until late: Early lung cancers are usually asymptomatic. They are found incidentally. When they grow and spread, then they may cause obstructiion of airway leading to shortness of breath, bleeding, phlegm and pneumonia. If it's spreaded, the it can cause pain in bone or in other organs involved.

Can be many: Typical symptoms of lung cancer can be unintentional weight loss, coughing up blood, chest pain, night sweats, and some fevers and even pneumonia. But, usually, when you get these symptoms, the cancer is quite advanced. That's the problem with lung cancer: usually, it starts so small that you don't have symptoms.
