Once liver cancer develops to the middle and late stages, it is basically incurable because the cancer cells have already metastasized and spread through the blood system and circulatory system, so it is impossible to treat the lesions radically through surgical treatment. For patients with intermediate and advanced stages of liver cancer, they can only be treated by radiation therapy, drug therapy and biological therapy to prevent accelerated deterioration of the disease and prolong their survival. Radiotherapy is to use radiation to kill local malignant tumor cells to inhibit their growth and reproduction to the maximum extent, while drug therapy mainly includes Ocitinib mesylate tablets, compound red bean curd capsules, hepatoflux tablets, etc. Biological therapies commonly used include interferon injection, interleukin-2, immune ribonucleic acid, etc.
