Yes I Have A Pressing Question I Have A Friend

yes i have a pressing question
I have a friend that has had heart cancer, she has had a few surgeries and chemo and for a while the cancer stopped but then in a check up they found cancer in the spleen so they did chemo but it didn't work and it moved to the liver, she is not having any more surgery or chemo and what i want to know is can nutrition help her now or is it too late, my gut tells me this is so and she doesn't have much time to live
