Welcome to healthcaremagic.
cancer that has spread to ling and liver is stage 4 diseases and unfortunately outcome is very poor for this stage.
an start in this stage at any time.
Main problem she will be facing are pain,jaundice ,fluid in abdomen.
There are strong pan medications like morphine
which can help her. For jaundice she might need stenting to bypass biliary obstruction.
or targeted therapy(tarceva) can be a option if she is in condition to tolerate treatment.
Hope this answers your query.
