Cholangiocarcinoma, also known as bile duct cancer, is a relatively rare form of cancer. Its incidence varies across different regions of the world. In general, the incidence of cholangiocarcinoma is higher in certain parts of Asia, particularly in countries like Thailand and Korea, where it is more prevalent due to specific risk factors such as liver fluke infection.

In Western countries, the incidence of cholangiocarcinoma is lower, but it has been increasing over the past few decades. It is estimated that cholangiocarcinoma accounts for approximately 3% of all gastrointestinal cancers. However, it is important to note that these statistics can vary depending on the specific population and geographic location.

If you or someone you know has concerns about cholangiocarcinoma, it is always best to consult with a healthcare professional who can provide personalized information and guidance based on your specific situation.
