this is more a post to ask advice…

my brother who is 48 was diagnosed with both lung and liver cancer two weeks ago. He fell ill, took himself to hospital whereby he was scanned and bloods taken.  
He had a liver biopsy taken, they told him that they believe the type of cancer it is has probably spread to his kidneys, bladder and pancreas. 

The oncologist has told him they can’t offer him treatment, he’s liver is more cancer than liver and he is too underweight. They’ve prescribed him ensure and told him to eat mainly protein and fat.  He tries to eat but finds it uncomfortable and lacks appetite.  He is very underweight, you can see his bones and the shape of his skull. 

he is at a pep scan today (I think that’s what it’s called) to see exactly where else it is.

i wonder if there is something they could offer him to promote his appetite? To help him to put weight on. 

I know they’ve said they can’t treat him with chemo but is there anything else they could offer? I know there isn’t a cure but isn’t there something they could offer to give him a better quality of life and hopefully to prolong his life? 

thanks in advance
