Hypofractionated liver cancer is not why stage, they are two different concepts. Liver cancer is a malignant tumor caused by hepatitis virus, heredity, alcohol and other factors. According to the degree of differentiation of the cancer cells and the stage of the tumor, more appropriate treatment methods and prognosis can be adopted. The classification criteria and concepts of the two are different, so please do not confuse them. Among them, the differentiation degree is obtained from the pathological examination of cancer tissues, and the differentiation degree of cancer cells can be classified into three grades: high, medium and low, and the higher the grade, the higher the degree of malignancy and the worse the prognosis. The staging is based on the development of primary tumor, the degree of lymph node metastasis, and whether distant metastasis occurs, and it can often be divided into four stages. The later the stage, the more complicated the condition and the worse the prognosis. Patients with middle or low differentiated liver cancer should actively consult the doctor and follow the doctor’s instructions for treatment.
