Cholangiocarcinoma is a rare, aggressive and deadly form of cancer that originates from the cells lining the bile duct and affects approximately 10,000 Americans annually. The Cholangiocarcinoma Foundation is the only non-profit organization in North America, and the largest global organization, exclusively dedicated to finding a cure and improving the quality of life for those affected by bile duct cancer. We provide supportive patient and caregiver services, a patient registry, research funding and an annual international conference.
