What are the specific hazards of bile duct cancer

Cancer is a terrifying disease. As we all know, cancer is extremely difficult to treat and is very easy to metastasize and recur. There are many types of cancer, and malignant tumors can occur in any part of the human body. Cholangiocarcinoma is a malignant tumor, so what are the specific hazards of cholangiocarcinoma?

The high incidence of bile duct cancer has gradually made more people pay attention to this disease. Therefore, it is necessary for us to take relevant preventive measures for bile duct cancer tumors, but most people do not understand the harm of bile duct cancer. Let's take a closer look at this issue.

Since the early symptoms of bile duct cancer are relatively hidden and difficult to detect, it is easy to be ignored and misdiagnosed, thus missing the best time for treatment, which makes its harm more serious. Biliary cancer will first cause bile duct obstruction in patients, which will lead to functional disorders of the bile duct system, and then cause digestive system disorders in patients, leading to anorexia in patients.

Biliary duct cancer can easily lead to liver failure, which is a very important reason for many bile duct cancer patients to die. Biliary duct cancer can also often lead to bile fistula. This is the most common and serious complication after bile duct cancer surgery. Because there are many openings in the intrahepatic bile duct, it is sometimes difficult to handle properly, making it easy for patients to have bile fistula after surgery.

The most common symptom of late-stage cholangiocarcinoma is metastasis, which is a dynamic and continuous process. First, tumor cells invade and break through tissue barriers to enter blood vessels and lymphatic vessels to form cell emboli, which then fall off and run in the blood or lymphatic vessels. Then, they adhere to the endothelial cells of the microcirculation of distant organs, stay there, and pass through the microcirculation, multiply in the parenchyma of new tissues and organs, and grow into new metastatic tumors.

In addition, during the metastasis of bile duct cancer, cancer cells can also fall directly into the body cavity. Implantation on the serosal surface forms implanted metastatic tumors. Biliary duct cancer metastasis mainly passes through lymphatic vessels, blood vessels and body cavities. Blood vessels mainly pass through veins, rarely through arteries first. Symptoms of late-stage bile duct cancer show that metastasis often starts from the lymphatic tract.
