I recently had a chest CT angiogram, and they looked at the surrounding organs as part of the scan. They found something that has me concerned. I have a family history of metastatic cancers. My paternal GM had multiple cancers (breast, lung, stomach, etc) and my father had prostate cancer (and possibly others).
I was also a passive smoker until my father passed away when I was 28. Both my parents smoked, however my mother stopped when I was in my teens due to an attack of emphysema.
What they found is that I have a 4mm nodule and additional 2-3mm pleural based nodules all clustered in the left upper lobe of my lung.
I'm concerned about this. Can anyone please shed some light on what this means and if there's a cause for concern?
