How does lung cancer people feel i mean i want to know how and what kinda body pains they go through?

Variable: Depends on cell type, location, stage, time of origin, and metastases from nothing noticed at all in early stage to the worst possible misery and pain and breathlessness! weight loss , cachexia, cough, bleeding, drowning in sputum, are all possibles. With spread, bone pain anywhere and paralysis can occur. Do not smoke!

Nothing early: Early stage lung cancer causes no symptoms. As the tumor grows, it can cause coughing or hemoptysis(coughing up blood). It can also cause shortness of breath if a portion of the airway is blocked off. Pneumonia can cause pain by irritating the lining over and around the lung. More advanced lung cancer can spread to other organs such as bone, brain, etc. Causing symptoms there. Don't smoke!
