Is My Grandma Going to Die?

My Grandma had a large cancer removed from her ascending colon about a year ago. Several lymph nodes contained cancer also. She had no evidence that it had spread anywhere else - liver , lungs and bones were scanned before the surgery. The oncologist felt that she was too medically fragile to get chemotherapy because she had 2 strokes right after the surgery. Now the cancer has come back in her abdomen. It is in her liver, but also spread all around the abdomen and is producing a lot of fluid. Is there any hope that she can be cured? If not, how long does she have to live? She is 91.
