I had a CT scan in April 2005, after a chest/abdomen x-ray showed the nodules described in the subject. A CT scan from March 2002 did not show these nodules. I am 36, female, never smoked, grew up in smoking household. Father's father died from lung cancer, was a smoker, father's mother treated for throat cancer, was a smoker also. I've been to a pulmonary specialist, and while waiting to see him, I browsed the notes from a conference the hospital has for people with nodules. I saw the word Wegener's and was wondering how likely it is that I have either cancer or Wegener's. I keep hearing these are likely benign, but I'm still worried.
