Do you know the common knowledge about bile duct cancer?

Do you know the common knowledge about bile duct cancer? When it comes to cancer, I believe that no one is not afraid. It is a difficult problem that the world is currently trying to overcome. The occurrence of bile duct cancer brings serious harm and will also bring considerable pain to patients. So, do you know the common knowledge about bile duct cancer? Let's take a look.

Cholangiocarcinoma originates from the extrahepatic bile duct, including epithelial cells from the liver hilar area to the lower end of the common bile duct. It ranks second among hepatobiliary malignancies, second only to hepatocellular carcinoma, and accounts for about 3% of digestive system tumors. Primary cholangiocarcinoma is rare, accounting for 0.01% to 0.46% of ordinary autopsies, 2% of autopsies of tumor patients, and 0.3% to 1.8% of biliary surgeries. In recent years, the number of patients with cholangiocarcinoma has increased, and the incidence rate in some cities has doubled.

Surgical resection is the best option for treating bile duct cancer, but the prerequisite for successful surgery is also early detection. Since the early symptoms of clinical bile duct cancer are not very obvious, scholars studying bile duct cancer in recent years have paid more attention to how to diagnose it early.

Cholangiocarcinoma is divided into intrahepatic cholangiocarcinoma and extrahepatic cholangiocarcinoma. Intrahepatic cholangiocarcinoma refers to a malignant tumor originating from the bile duct epithelial cells below the secondary branches of the intrahepatic bile duct, accounting for about 10% of cholangiocarcinoma. It is highly malignant, has hidden symptoms, and has a poor prognosis. Because the disease is located in the liver and is similar to hepatocellular carcinoma in some clinical aspects, many domestic textbooks and reference books discuss it as a type of primary liver cancer.

Extrahepatic bile duct cancer refers to primary malignant tumors of the left and right hepatic ducts, the common hepatic duct, and the common bile duct above the pancreas. Progressive obstructive jaundice is the main clinical symptom of extrahepatic bile duct cancer, and its cause has not yet been determined. About 16%-30% of extrahepatic bile duct cancer patients are accompanied by gallstones, so chronic stimulation by gallstones is considered to be a possible carcinogenic factor.
