Before i answer your question, let me inform you that i am an experienced oncologist
and have been working at a dedicated cancer hospital for some time now. Let me make a few things clear to you before i move on to the specifics. Maybe you know them already, but nonetheless. Firstly, your aunt cannot be cured of her disease by any form of treatment. Secondly, the treatment that she has undergone so far before this admission seems to be largely correct from an oncological point of view. Finally to your query. Treatment at this point is aimed only to provide her a good quality of life and to prolong whatever life we can. From what i gather she has gross ascites
and her liver
is failing as well due to the disease. So she would benefit in terms of pain by draining the fluid from her abdomen, although it will re-accumulate quickly and need frequent draining. Also, since her liver is failing and platelets are low, this draining procedure will have to be done after correcting her bleeding profile by transfusing plasma and platelets. In short, she will benefit from shifting to a cancer hospital. However two things you have to consider before shifting are whether she is in a condition to be shifted and your finances.
