Small nodule found when lung xrayed
Hi. My 35 year old friend just had a lung xrayed, as she thought she might have pneumonia. Apparently the xray does not show signs of pneumonia. However, the xray did show some sort of nodule, which is, apparently, less than 1 mm.
My question is......is it possible to even see something so small on an xray? From anything I've read, a nodule would have to be at least 1 cm to even be visible on a normal chest xray.
I'm really hoping it's possible to see something so tiny, but am now wondering if perhaps my friend is confused as to what the doctor said. Maybe he said 1 cm, rather than 1 mm.
Also, the doctor didn't appear concerned. If it truly is only 1 mm, is that really of no concern at all? and would something so small be a common finding on many people's xrays?
Thanks for any advice you can offer.
