Lung Nodule information

I just wanted to tell you all my recent experience with a lung nodule.  I am a 38 year old nonsmoker.  I had pulmonary function tests and a CT scan last year because my asthma was flaring up during allergy season.  The pulmonary function tests were all very good but I had a 3mm nodule on my lung.  The pulmonary doctor told me at the time that it was nothing to worry about and to get it checked again in one year.  I just had the follow up CT scan last week and it did not grow and has been therefore determined to be benign.  The doctor told me that CT scans are so powerful that they detect these benign, small nodules in a large amount of patients.  He said if you took 100 people off of a bus who had no symptoms and gave them a free CT scan, a large number would have benign nodules.
