What are the predisposing factors for bile duct cancer? There are many predisposing factors

There are many factors that induce bile duct cancer, the most common ones are: bile duct stones, sclerosing cholangitis, parasites, etc.

1. Bile duct stones <br/>About 1/3 of bile duct cancer patients have bile duct stones. There is a 5% to 10% chance of developing bile duct cancer. If bile duct stones are not cured for a long time, the chance of cancer is even higher. After bile duct stones occur, the bile duct wall is repeatedly stimulated, causing changes in the bile duct wall mucosa. If the bile duct wall proliferates, it is very easy to become cancerous.
2. Sclerosing cholangitis <br/>It may be a precancerous lesion of bile duct cancer. It is caused by thickening of a section of the extrahepatic bile duct, which leads to local stenosis. The entire section may also thicken and stenosis. Long-term development may induce bile duct cancer.
3. Parasites <br/>It is an infection with Clonorchis sinensis, which can easily cause liver and gallbladder system diseases. The chance of causing bile duct cancer is 4.5 times that of normal people, and is higher in men than in women.
