Can you please lay out the initial symptoms of lung cancer?

Frequently none: What makes lung cancer so devastating and deadly is that, frequently, there are no symptoms until it is too late and the cancer has already spread. That's why...You shouldn't smoke in the first place or quit smoking if you are smoking. The best way to avoid lung cancer is to not smoke.

From nothing: To terminal. Early on, no symptoms. May be identified on x-ray or ct for something independent. Cough hemoptysis- coughing blood pain in apex or chest wall shortness of breath. Progress from tiny, to small stage 1, to local spread to lymph nodes, to spread with distant metastasis stage 4.
