International St. Mary's Hospital provides Cholangiocarcinoma (Bile Duct Cancer) Treatment using contemporary hepatobiliary and oncology techniques and evidence-based care. Founded in 2014, the JCI accredited hospital is based in Seoul, South Korea, with 808 beds and services for domestic and international patients.

The treatment approach depends on whether the cancer is intrahepatic, perihilar, or distal bile duct cancer and whether it can be surgically removed. Depending on the diagnosis, treatment may involve liver or bile duct surgery, chemotherapy, radiation, targeted therapy, or immunotherapy. Imaging, pathology, and molecular profiling help guide treatment planning.
