My gma has stage 4 liver cancer?

My husbands gma is 96 and has been diagnosed with stage 4 liver metastasis, large quantities of tumors in her lungs and swolen lymph nodes. she is going to a skilled nursing facility and is also going to be starting hospice care while there, as she has requested there be no treatment given. The dr. said the outlook is anywhere from 2 mo - 1 yr, but we live 1000 miles away and didn't know if there was even a smaller time frame we are looking at. She is already suffered huge weight loss and is yellowing, however the dr said it was a "slow growing" cancer - pain is only to the touch of the abdomen, but she had a masectomy 10 years ago for cancer, and about 4 years ago she had tumors in her urethra and received some kind of radiation treatment. She has bacteria in her lungs that the dr says will never clear up she has not responded to 3 different types of antibiotics. Any info would be great. We just don't want our sweet grandma to suffer.
