Aussie,

I will also jump in here to say that I have one of those nodules in my lung. It was first picked up about 3-4 years ago. Like you, I was a bit freaked at first. After consulting with a radiologist and my primary, it seemed clear that the best thing to do was to watch and wait - just like the others here are doing. If it does change in size, then I will get a biopsy. I had it checked every 3 months for awhile, then every 6 months, now it is once a year. So far . . . no changes . . . hopefully, it will stay that way . . . and I wish the same for you.
