What is the most terrifying thing about bile duct cancer

What is the most terrifying thing about bile duct cancer? Biliary duct cancer is a malignant tumor. The most terrifying thing about bile duct cancer is the metastasis in the late stage. Once it metastasizes, it is very difficult to treat and the disease is difficult to control. Therefore, when you feel unwell or have suspected symptoms, you should go to a professional hospital for examination and diagnosis. Let's follow the editor to understand how it metastasizes.

One of the main reasons why malignant tumors are difficult to cure is that they have the characteristic of metastasis. The most important symptom of late-stage cholangiocarcinoma is metastasis.

(I) Transfer process

The most common symptom of late-stage cholangiocarcinoma is metastasis, which is a dynamic and continuous process with many stages. 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. They then adhere to, stay in, and pass through the microcirculation endothelial cells of distant organs, multiply and grow in the new tissue and organ substance to form new metastatic tumors. In addition, during the metastasis process, cancer cells can also fall off directly into the body cavity and implant on the serosal surface to form implanted metastatic tumors.

2. Transfer pathways

The metastasis of malignant tumors mainly occurs through lymphatic vessels, blood vessels and body cavities. Blood vessels mainly pass through veins, and rarely through arteries first. Symptoms of late-stage cholangiocarcinoma show that metastasis often starts from the lymphatic tract.

Lymphatic metastasis: Lymphatic metastasis mostly follows the pattern of lymphatic trunks, namely the left and right head and neck trunks, the left and right subclavian trunks, the left and right bronchomediastinal trunks, the left and right lumbar trunks and the intestinal trunks.

Hematogenous metastasis: Hematogenous metastasis is mainly divided into systemic vein type, pulmonary vein type, portal vein type, pyramidal vein type and countercurrent type.

Implantation metastasis: Tumor cells diffusely grow in cavities, such as the thoracic cavity, abdominal cavity, pericardial cavity, etc. Surgery and puncture procedures can also cause implantation metastasis.

The above is an introduction to what is the most terrifying thing about bile duct cancer. I hope it will be helpful to you.
