Cholangiocarcinoma is a highly malignant tumor, which must be treated by surgery, because cholangiocarcinoma is not well treated by radiotherapy, and is prone to recurrence or spreading of cancer cells. When bile duct cancer is found in early stage, the volume is small, and often the cancer cells have not spread or metastasized, then radical cholangiocarcinoma treatment is needed to remove the tumor cells cleanly, and then send the pathological biopsy to clarify the nature of the tumor after the operation. After surgery, bile duct cancer patients need to pay attention to their diet, eat easy-to-digest food, eat more fresh vegetables and fruits rich in vitamins, eat less high-fat and high-cholesterol food, and eat more protein-rich food, which is helpful for the recovery of patients’ condition. During hospitalization, if there is any discomfort, report to the doctor in time so as not to delay the treatment.
