Re: lung cyst
While I understand your concerns with having a cyst in your lung, be careful before you start accusing the radiologist of "playing God". Doctors have a LOT of training in what they do, and contrary to what many people think, being a doctor is much more than just pattern recognition and educated "guessing".
Radiologically, lesions which tend to be malignant have certain stereotypic appearances on the scan. There are certain features like shape, size and internal characteristics which can alert the radiologist to the possibility that what you have may be malignant. You're right that no one can be 100% sure, but in life, you can't really be 100% sure about ANYTHING; however, in your case, cysts in general are rarely cancerous, and the "pre-test probability" of this being cancer is <1%. Now look at the risk associated with a lung biopsy and it greatly outweighs the benefit of doing a biopsy. Your doctors will likely redo the CAT scan in a few months and if the cyst has changed in appearance (which is unlikely) they may need to do something about it then. It's difficult, I know, to sit back and trust the doctors (especially when we live in a time where we are all encouraged to be advocates for our own health), but docs do a LOT of training to get where they are, and putting your trust in them to do their jobs is the same trust you put in a pilot to get you to your destination safely when you're flying in a plane.
