Comparing Lung X-Rays

I'm a patient… had melanoma mets in the lung. My dad passed from lung cancer. His lesions looked more "cloudy"… almost misty with fuzzy edges. My lung lesions were pretty clearly delineated "globs". That said, I'm not sure how different lung cancer types might appear on xray or CT imaging. On a more positive note, a friend who recently underwent a biopsy for a 4 cm lung lesion she feared might be metastatic breast cancer, learned that what she's growing is a lung fungus, and not a cancer at all! Not that we all wish for lung fungus… but when one can be treated with antifungal pills, rather than potentially suffering from cancer… it's time to cheer. I'm not sure you docs would be able to tell simply by viewing xray or CT imaging. I would think a biopsy is needed. But again… I'm a patient… not a doc or radiologist… soooooo. Are they aware of your melanoma history? 

I learned from the surgeon that “would have” been my lung surgeon (surgery canceled due to desease progression) he reassured me even before my lung biopsy (wich confirmed melanoma) that my CT scan report showed him “melanoma” as dark, defined “ball” like tumors & he said NSCLC type lung cancers is more globby & shadowy on ct scans..

Only one way to find out, stick a needle in there and take out a sample. I must say it is not one of my most favourite things to do. I go to a teaching hospital and listening to the expert doc explain to the student about to do the procedure " why that angle won't work, you need to go at it from this angle" kind of makes for a sport experience!!!
