My mother has breast cancer, but it has spread a lot. She was diagnosed June 2018. This is the last line of treatment they are planning to use on her, and they are halfing the dose as she has quite bad liver mets. Due to her liver problems, she was recently told that without chemo she may only have a fortnite. She has it in her lungs, liver, brain, spine too. If you have experience/ more knowlege about this drug does it increase life expectancy? The consultant said it could by some months if successful. 

Also, with symptom control she is taking some medication, such as steroids and morphine. Is there any other way we can protect her organs e.g via diet, IV medication etc as I am very worried about her health right now. 

Thank you and good wishes.
