Thanks for the query to H.C.M. Forum.
In my opinion the black shadow in the kidney area may be due to tumor or solid mass . Diagnosis can be confirmed by biopsy
of the part.
2nd thing the shadow in the lungs is due to solid mass ( may be secondaries due to kidney mass ) in kidney area. Diagnosis will find out the exact nature and type of this mass .
3rd point is pain in the stomach , this may be due to peptic ulcer disease
. Diagnosis can be confirmed by upper G I endoscopy
. However try raising the head of bead 4 inches with blocks help.
Avoid greasy , spicy food .
In ,my opinion first of all consult an Urologist
and get his opinion regarding kidney shadow and there after deal according to situation .
If kidney shadow normal as due to cyst then consult a pulmonologist
and get his opinion and deal accordingly .
Only question is whether this black shadow is cancer or not.
Good luck for your mother . Dr. HET
