bilateral multiple lung nodules

I have read on Google that these are most commonly caused by mets. Mine are. 4 and 5 mm, one in each lung. Is the information I read correct and they are likely mets? I have no symptoms of a tumour elsewhere and no fatigue or weight loss. Nodules found incidentally in a ct for rib pain that I paid for. It was not requested by my doctor. I have posted before but am scared. Are small nodules unlikely to be malignant even when they are bilateral?

[David Tinkelman, M.D.]

Clearly, all large nodules were, at one time, small nodules but, at any given point in time small nodules are unlikely to be malignant, even when bilateral.  Nodules associated with infectious and/or inflammatory disease are just as likely to be multiple, as to be solitary, This is especially so in a young person without any obvious risk factors and no sign of tumor elsewhere, no fatigue and no weight loss.  But, do try to locate previous chest X-rays for your Doctor to have a source of comparison and be able to offer optimal diagnosis.
