What are we looking at?

Hello, I am new here and needing some insight, hope in what we are up against.
My Mom who is 79 and otherwise healthy went to the ER for some abdominal pain. They did extensive test including MRI, CT with and w/o contract that revealed a mass on the pancrease and on the liver. The labs that were done the pancreas, ( which I am unsure what it is called) was very high, if I am correct normal is up to 135 and hers was in the mid 400's. She has had on and off cloudy/dark urine and has lost 20 pounds. All of this started about a month and a half ago.
She just had an upper endoscopy to get biopsies but the DR is pretty certain that it is cancer. She is scheduled to have a stent placed. So currently we are awaiting results but in the mean time my Mom has no appetite, she tries to eat light things but it's hard, she is getting weak and fatigued.
I have no idea where we are on this but is there hope for her? Looking up information it doesn't look good and I am so scared. Any advice or information is greatly appreciated. Thank you
