What are the types of bile duct cancer? There are many types of types

There are many ways to classify bile duct cancer, mainly based on the site of occurrence, histological type, and pathological gross morphology. The classification can help understand the progression of the disease and choose treatment methods.

1. Location of bile duct cancer <br/>It can be divided into hilar cholangiocarcinoma, intrahepatic cholangiocarcinoma and common bile duct cancer. The incidence of hilar cholangiocarcinoma is relatively high, accounting for about 60% of the incidence of bile duct cancer.
2. Histological type <br/>It can be divided into adenocarcinoma, squamous cell carcinoma, carcinoid, adenosquamous carcinoma, etc., among which adenocarcinoma accounts for more than 95%. It can be further divided into well-differentiated adenocarcinoma, poorly differentiated adenocarcinoma and undifferentiated adenocarcinoma. Well-differentiated adenocarcinoma is more common, while poorly differentiated and undifferentiated adenocarcinoma are rare.
3. Gross pathological morphology <br/>It can be divided into nodular carcinoma, papillary carcinoma and diffuse carcinoma, with nodular adenocarcinoma and papillary carcinoma being the more common.
