A friends mom has just been diagnosed with Stage III ovarian cancer that is also in the adominal lining. She is 90 yrs. old with a pacemaker and very high blood pressure issues. They sent her to Hospice from the hospital after entering with chest pain and SOB, she is refusing any chemo or treatment. How long can our friend expect her to survive? He is out of state right now and is trying to determine when he should return to be with her.
