This is Dr. David
yes, a shoulder MRI scan of the shoulder would show if he had a pancoast tumor in his right upper lobe lung.
a chest xray would show also a pancoast tumor.
these are rare tumors
much more likely arthritis and his weight lifting is causing his right shoulder pain.
he should try to ice the shoulder and also lift lighter weights.
his symptoms would not be caused by a pancoast tumor
