Liver Cancer - I need help!

Our close friend has been diagnosed with lymphoma. After discussing alternative treatment...his wife was in total support of trying to bring him back to health via alternative methods. She began preparing & following Budwig's flax diet etc., and attempting to give her husband Essiac as well. This was short lived as everything he drank/or attempted to eat was quickly brought up. My question to anyone who has suggestions. What do you do when you can't keep anything down? Tonight, he was brought back to hospital...stomach is out like a balloon and they want to do chemo. She wanted to avoid this..but is at a loss..
