I had a productive cough in April and I went to dr. I had a Ct scan and they discovered a 3mm lung nodule. The pulmonologyst said she saw at least 4 more but they are so small the were not mentioned by the radiologyst. I quit smoking (24 yr- 15 cigarette a day) in June after I found out. The withrawal is horible, the anxiety is above sky, back pain , shortness of breath you name it. I am spending hours on internet trying to figure out if I have lung cancer or not, I am due for another Ct scan in January, but till then it will help to have an opinion. thanks
