These findings are commonly found with a variety of interstitial lung diseases (ILD). This is swelling that leads to scarring of the lungs in the area between the air sacs and the blood vessels. Please read our Interstitial Lung Disease MedFact at http://www.nationaljewish.org/medfacts/interstitial.html for further information.
You will probably need a lung biopsy. This provides the specific answer that the CT scan cannot. During a lung biopsy tiny pieces of lung tissue can be taken for further testing. A lung biopsy is done to be certain about the diagnosis. Only then is it possible to say what treatment would be most helpful. Further testing that may be done are pulmonary function tests (PFTs). These are a variety of breathing tests that provide detailed information about how your lungs are working. Until your specific diagnosis is known one can only speculate. However since you are a non-smoker, age 37 there is a strong likelihood that this will prove not to be cancer.
Hi browneyedgirl,
One possibility you will want to look at is sarcoidosis, which is a systemic disease. You can learn more about this disease at www.sarcinfo.com. Be sure to follow up on this with your doctor. Sarcoidosis patients are generally non-smokers.
