Hi, This is the case of my mom-in-law. She was operated for breast cancer in 2008 and it spread to her liver?

Metastasis to liver and bone in Oct 2010. She was doing okay but since last two months, she has gone drastically down with weight loss, general weakness and latest was feeling drowsy and slept for long hours during day. Last week, She vomitted on two separate days, some loose motion too, and edema - leg swelling. Sonograph revealed fluid in liver and yesterday extracted around 3.5 litres of fluid as she could not have any food at all. Now we understand that she has to be repeatedly drained. Jaundice was seen a week before this in eyes and it later disappeared. Yesterday, her face and hands and slowly mostly all parts of body is yellow. Doctor says liver is not functioning normal and she has only` few weeks to few months.' Please help me by advising what else should I expect will happen as I feel she should not suffer much. She has thinned so much. Will she have lot of pain due to this liver malfunctioning ? Will the bones give her hard time ? How fast will the fluid accumulate ? Will the jaundice affect the heart since bilirubin is high ? Sorry, i asked so many questions. This will also help me extend my leave and care for her. Thanks for your valuable answers, dear brothers and sisters.
