[|Human|] i am 22 and i have smoked a little less than a year. I average around 3 - 4 a day. rarely do i smoke more then that. I have a nagging cough that comes and goes throughout the day. There is never any blood. But it feel kinda like I have a little mucus in my chest I need to cough up...not heavy like when I really sick, but light. other then that, I have no other real symptoms. no chest pain or blood. Im tired a lot but I kinda think Ive always been like that since Im not in shape.I already know it CAN be a sign. I have decided to quit.  (been 4 days and getting easier)and I know there is always a risk.What I want to know is, given the info i just gave you, do you think its likely that I have Cancer? Or just irritated lungs?
[|AI|]  Hi and thank you for sharing your concern in Chat Doctor. I read carefully your question. In my opinion as a chest physician i don't think you need to worries about cancer since from the symptoms you describe, your age , your smoking history, the possibility is very low to nothing. I would encourage your decision to quite the cigarette since smoking is a strong risk factor of lung cancer, lung disease, heart disease. I wish you good health. Kind regards Chat Doctor.
