Hello, my grandma has advance lung cancer spread to her bones and brain, she has been admitted to hospital today after being sick a lot this morning, and she has been sick a green liquid this evening, she has not been offered any treatment as her cancer is so advanced, she has been cleared for any infections but has been told she can t go home until her sickness is under control.. We believe she is in her last few days and are desperate to get her back home, are there any reasons why she would be being sick what looks like bile when she has been eating fairly well? Thank you
