new to all this

My mom has finally been diagnosed with CC. She presented with sever jaundice about nine months ago. Now from what I have read this disease is very aggressive and the doctors told me that there has been no change in the one spot they found. Size is the same and it has not spread. This does not make any since to me. She has a very good primary dr and he agrees with me. Nothing adds up.
She had a biopsy done so we are pretty sure this is what she has. I still have to discuss with her primary doctor as to what the next step is. We know that surgery is not an option for her due to her medical history(3 strokes & needs triple bypass surgery) Is there anything I should be asking the doctor ? Any help would be greatly appreciated
