when i was age 3 to about 7 or 8, i lived with my step mom who smoked all day, every day. i didint know at the time how bad it was and i would be by her constantly inhaling 2nd hand smoke. Now im wondering if i should get checked or not.

stupid me, also smoked off and on from 9th to 12th grade, and a few times smoked marijuana.

ive always had problems breathing and such since i was very young and im 18 now, should i get checked, what are the symptoms?

It would be extremely rare, almost never heard of, that a person your age would have lung cancer. The early symptoms of lung cancer are a persistent cough that lasts for weeks. if your breathing difficulties are distressing to you – your family physician can check that out for you with a quick listen through a stethoscope. Stay away from cigarettes and weed – both can cause cancer.

coughing and you can't hardly breathe I hope you go to the doc ,
