Biological tumor therapy is a treatment method that aims to kill tumor cells by adjusting or stimulating the body’s own immune system through various effective methods, and such methods are characterized as green, safe and effective. Indications: All malignant tumors are indications for biologic therapy, except for T-cell-derived lymphoma, which is not suitable. All tumors that meet one of the following conditions are suitable for biological therapy: 1. Early stage tumor patients: In addition to surgery, radiotherapy and other treatment methods, early diagnosed tumors should undergo biological therapy to give full play to the characteristics of biological therapy, enhance their own immunity, and kill tumor cells most thoroughly. Especially for some very early stage patients, there is no need for chemotherapy and radiotherapy after surgical resection, so biological therapy can play its best effect at this time. 2.Patients after surgery: 2 weeks after surgery is the period when the immunity of the body is the lowest, and the scattered and remaining tumor cells can breathe and proliferate at this time. 3.Patients with radiotherapy: Whether it is radiotherapy or chemotherapy, while killing tumor cells, it will inevitably cause great harm to the immunity of the body, at this time, if biological therapy is carried out, it can make the body fight against tumor cells together with radiotherapy, so as to enhance the efficacy of radiotherapy and reduce the side effects of radiotherapy. 4.Patients with poor status and unable to tolerate surgery and radiotherapy: At this time, patients with poor status and immune function completely suppressed by tumor are not suitable for intense treatment. At this time, if biological therapy is carried out, it can effectively activate the body’s own immune function without side effects, kill tumor cells to a certain extent, minimize patient’s pain, prolong survival time and improve survival quality.
