Most tumors have no specific symptoms in the early stage, and once they are detected, they are already in the middle and late stage, and lose the opportunity of surgical treatment. Radiotherapy becomes a necessary treatment. In the early stage of the disease, most of the patients are still able to withstand radiotherapy, and the effect of radiotherapy to inhibit tumor growth is also very obvious. However, as the tumor progresses and the body is hit by radiotherapy again and again, the patient’s body becomes weaker and weaker, so the treatment can no longer be continued. At this time, however, there are many patients and even medical workers who do not understand the importance of joint application of TCM. TCM believes that tumor is a chronic wasting disease, and most of them are deficiency evidence. Fu Zheng Pei Ben method is a common method in the treatment of tumors in TCM. The application of Fu Zheng Pei Ben method can support the body’s positive energy, adjust the yin and yang bias, supplement the body’s weak state, adjust the body’s internal environment, improve the patient’s immune function, strengthen the ability to resist and get rid of the disease, inhibit the growth of cancer cells, and create conditions for further treatment. Modern research has concluded that the effects of fostering and cultivating the essence of cancer control are multifaceted: 1) improving the cellular and humoral immune functions of the body; 2) protecting the bone marrow, enhancing the effects of radiotherapy and controlling recurrence, thus achieving the effects of anti-cancer and cancer suppression; 3) promoting the phagocytic function of the reticuloendothelial system and improving the immune status; 4) direct tumor suppressing effects .
