For a year and a half I have been monitoring nodule on the lung. Have been to two Pulmonary specialist. I have a CT Scan every 3 months. I was also told I had a mass but then told the mass could be scar tissue. Now I have been told I have two more nodules since my last CT Scan a week ago. Now I have three. They have told me it can be an infection or something. I am not comfortable with all this please advise. I also smoke. Trying to quit cut down to 1/2 or less a day now.
