Dr. I Just Found Out My Auntie Has Gall Bladder

Dr. I just found out my auntie has gall bladder cancer. She is losing alot of blood and was getting blood transfusion for the past month and her body is not containing the blood. The doctors are deciding that her outlook is not good so they will not be giving her any more transfusion. I was told the stage of cancer is 4 and I just can't believe there is nothing eles that can be done to help preserve her life. I need someone to explain this process. Because just to stop giving blood to someone and let them die is unbeliveable to me.
