About World Cholangiocarcinoma Day

World Cholangiocarcinoma Day is a global awareness campaign for cholangiocarcinoma, a cancer of the bile ducts. Current campaign materials place the day on the third Thursday in February.

The day raises awareness, supports people affected by the disease and encourages research and informed care. Awareness information cannot diagnose cholangiocarcinoma or determine treatment for an individual.

Why World Cholangiocarcinoma Day matters

The observance helps patient groups, clinicians, researchers and supporters bring attention to a relatively rare cancer and the needs of patients and caregivers.

Symptoms associated with bile-duct cancer can overlap with many other conditions. People should not self-diagnose from an awareness list, and screening or treatment decisions require appropriate clinical evaluation.

History of World Cholangiocarcinoma Day

The Global Cholangiocarcinoma Alliance states that AMMF – The Cholangiocarcinoma Charity set up the inaugural World Cholangiocarcinoma Day in 2016 with partner organizations.

Alliance history says a 2018 international workshop brought advocacy groups and specialists together and helped give rise to the Global Cholangiocarcinoma Alliance.

A 2023 campaign guide states that the day had previously been February 12 and, from 2023, moved to the third Thursday in February.
