Non Calcified Lung Nodules?

I am a 35 year old female with no history of smoking, other than second hand smoke from my parents when I was a child. For 2 years now I have had 4 very tiny non calcified lung nodules. Histoplasmosis (sp?) was expected but the lung specialist said that they would calcify if this is what they were caused from. He also said they are too small to biopsy. Can you tell me what is usually done when nodules continue to not calcify? And if they are too small to biopsy? So far I have had ct scans every 6 months, with the same results.

Thank you!

To reassure you, in my experience, your follow up care sounds pretty standard. This is what I found from the experts:
If the non-calcified nodules seen on screening were confirmed and were non-calcified on the diagnostic CT, further work-up was recommended, depending on the size (average of length and width) of the nodule:
nodules 5 mm or less: follow up with high resolution CT scans at 3 mos, 6 mos, 12 mos and 24 mos as long as there was no growth. http://www.journalclub.org/vol2/a71.html

If a nodule is found on a screening CT scan, than a decision is made to either biopsy the nodule if it appears suspicious for cancer, or to repeat a CT scan within 6 to 12 weeks to determine if the nodule has grown. Should the nodule grow, this is highly suspicious for malignancy, and a recommendation to biopsy the nodule is warranted. If on the other hand the nodule remains stable in size, and does not change, then continued observation is recommended. http://www.columbiasurgery.org/divisions...

As long as the nodules are too small to biopsy and they remain uncalcified, you will just follow the same course of action as you are following now: ct scans every 6 months. The purpose of the scans is to monitor the status of the nodules. Each status quo scan is very good news.

The RN is correct. Any lesion in the lungs that are small and not growing are typically benign and will remain as such. Again, the repeat CTs will look for any changes in them. If they detect any changes, they may want to biopsy at that time.

Any insult, damage, or inflammation in the lungs can cause tissue or scar growth in them. These small nodules were probably some damage from something you inhaled at some point in your life. Since they are stable and small, there is probably nothing to worry about.
