    ### Instruction:
    What is the outlook for Bile Duct Cancer (Cholangiocarcinoma) ?
    ### Response:
    Certain factors affect prognosis (chance of recovery) and treatment options. The prognosis (chance of recovery) and treatment options depend on the following:         - Whether the cancer is in the upper or lower part of the bile duct system.     - The stage of the cancer (whether it affects only the bile ducts or has spread to the liver, lymph nodes, or other places in the body).
