Need vs safety: The average background radiation exposure is a bout 2 msv (millisievert)/yr, and an average pet scan uses 5-7, ct=6.5-8, chest xray=0.02, and an aircrew member 4-9/yr, for comparison. It is hard to tell how many pet can be safely done--if you need it and the benefit outweights the risk, it does not matter how many. Talk to your doc/oncologist/radiologist--they know your case best. Good luck.

Probably not: I'm sure the doctors who are seeing you have very good reasons to want to re-evaluate your nodule, and it seems quite reasonable. They probably want to be aggressive and detect any change as early as possible.

Check with your doc: You can always see another pulmonologist for a second opinion.

Probably not.: I would worry much more about the lung nodule than i would the quantity of scans.
