how likely is a non-contrast high-resolution ct of the entire chest (not selective thin slices at random regions) to miss lung cancer when symptoms (e.g. shortness of breath, cough) are present?

Radiologist: A radiologist would know the statistics of the sensitivity and specificity of that type of imaging. I would expect it to be unlikely that such an imaging procedure would miss a growth, but a biopsy would still be required to diagnose cancer with certainty.

Cancer: For cancer to cause shortness of breath it has to be advanced. It is highly unlikely it would have been missed 3mo ago if it were that bad now.

Very small. CT: resolution is down to the millimeter range, so I think it would find the tumor and visualize it,especially at this stage w/weight loss and fatigue.
