My mom is 72 years old and is undergoing chemo & radiation for a mass on her left side outside of her bladder. She also has a nephrostomy bag on her left kidney because the mass is pressing against her ureter preventing urine release. She will not eat at all and she only drinks about 15-20 ozs of water & 1/2 half a Boost daily. She has lost about 5 pounds in the last week and weighs about 80 pounds now. What can we expect next?
