Hi, I am 22 years old male. I have been smoking (a pack a day) for 2 and half years. recently I started cold and coughing. not dry cough. there is a little bit of blood in the sputum , only in the morning after i wake up. i got 3 pneumonia when i was little. my lung is sensitive. now when i cough my back hurts(this symptom just occured yesterday).... but when i dont smoke it gets better. do i have possibility of getting lung cancer?
Thnak you!
