A member asked:
Fatigue for 2 years with some muscle loss. pet/ct scan was negative. what is chance of it missing lung cancer (exsmoker sorry, clean 2 years). thanks?
A doctor has provided 1 answer
Not zero: But very small. No test is perfect. There are a number of reasons for missed diagnosis of lung cancer. However, a PET CT is the best way to identify lung cancers. Not all nodules seen on CT are positive on PET but this is rare. If no nodules are seen on PET or CT, then the likelihood is less than 2-3/10,000. If you are worried, you can have a follow up low dose screening CT. PET is not needed.

A member asked:
What's the chance of an occult lung cancer causing 7 years of fatigue and other non specific issues but not showing on a CT scan of the chest. Thought about paraneoplastic syndrome but these seem very rare & cancer normally appears within a few years?

Fatigue, excessive sweats & muscle loss for over 4 years. Could it be paraneoplastic syndrome from lung cancer. Ex smoker. HR CT unremarkable Jul 2018
Would you expect a small cell lung cancer that was causing fatigue and muscle loss to be picked up on a low dose CT scan.
