[|Human|] My sister in law was just diagnosed with stage 4 bile duct cancer. She just went through with a hysterectomy because they thought she had ovarian cancer, she hadnt been holding anything down since being sent home from surgery and was taken to ER where they ran tests and told her stage 4 bile duct. They want to treat with chemo staying this week for 6 weeks. The cancer has spread to many places already. What can we expect,  YYYY@YYYY
[|AI|]  Hi and welcome to Chat Doctor. I am sorry about such serious disease. This is obviously terminal stage and one of the worse cancers. Unfortunately prognosis isn't very good, it is always hard to predict, but you have to do everything you can include chemo which can prolong life expectancy for 3-6 months. Usually 1 year survival is found in less than 5%. She can benefit from palliative treatment of pain, nausea NAD fatigue. Everything else isn't in your hands. Wish you good health.
