Brain tumors can occur at any age, with 20 to 50 years old being the most common. In adults, gliomas of the cerebral hemispheres are the most common, such as astrocytoma, glioblastoma, and ventricular meningioma, followed by meningioma, pituitary tumor, craniopharyngioma, and neurofibroma, etc. In children, tumors of the posterior cranial fossa and midline are more common. In children, tumors of the posterior cranial fossa and midline are more common, mainly medulloblastoma, craniopharyngioma and ventricular meningioma. “The brain is the sea of medulla oblongata, which is the capital of the spirit and the place of the clear orifices, and its position is high and belongs to yang. If yang qi is abundant, yin evils can not enter; if yang qi is weak, evils will take advantage of the weakness to enter the brain; wind evils and fire evils are most likely to offend the head and enter the brain. When the positive qi is weak, the clear qi does not rise and the wind and cold invade, the turbid yin does not descend, and the yang qi is blocked and becomes lesions in the medulla oblongata. Therefore, the beginning, evolution and formation of brain tumor are caused by the misbehavior of yin and yang of the organism, disharmony of internal organs, and condensation of phlegm and toxicity. The coagulation of phlegm and toxin, internal movement of liver wind, stagnation of qi and blood, and deficiency of positive qi are the pathological basis of brain tumor, and clinically, these pathologies are often related to each other and compounded to cause the disease, which makes the condition difficult to be saved and cured. Weakness of positive qi is of vital importance in the evolution of this disease, as the ability to resist disease is low and cannot resist the attack of external evils, the cancerous tumor is thus born; and this is the condition and basis for further spreading and expansion. Patients with advanced stage of brain tumor often suffer from illness due to deficiency, or the illness causes deficiency, forming a vicious circle; or after surgery, radiation and chemotherapy, the qi and yin are greatly injured, the positive qi cannot be supported, the heart and spirit are dissipated, and the spirit has no support, leading to coma. Brain tumor can be divided into early, middle and late stages. In the early stage, the tumor is still small, the positive qi is still strong, the stasis is not deep, and the patient should be attacked as the mainstay, or attacked and supplemented, or attacked and then adjusted; in the middle stage, the tumor develops to a certain degree, the positive qi is also injured, but the positive and the evil are in the stage of “evenly matched”, so it is appropriate to attack and supplement and give equal importance to it; in the late stage, the tumor has increased to a serious stage, the positive qi and the evil are full of weakness, and the patient is not responsible for the attacking and attacking. In the advanced stage, the tumor has increased to a serious stage, the positive is deficient and the evil is prevalent, the patient is not allowed to attack and conquer, so it is better to support the positive mainly, and use fewer drugs to dispel the evil. Brain tumor should be treated in early stage so that the therapeutic effect can be guaranteed. As far as treatment means are concerned, early malignant brain tumor with small cancerous tumor should be surgically resected if the site is suitable. If it is difficult to remove the cancerous tumor, radiotherapy can be carried out first, and then surgery can be carried out after the cancerous tumor becomes smaller. In addition, as the treatments of western medicine will cause different degrees of damage to normal cells of human body, clinics mostly advocate the combination of Chinese medicine treatment in order to increase the effect and reduce the toxicity. Due to the differences in theoretical system and clinical practice of Chinese and western medicine, the treatment of malignant brain tumor has its own characteristics and strengths, and the correct selection of these two means can play the purpose and role of mutual enhancement and improvement of tumor therapeutic effect. Combined traditional Chinese medicine treatment of brain tumor has better advantages: using traditional Chinese medicine before surgery can improve the functional state of the body and enhance the physical condition; after surgery, it can be used to benefit qi and consolidate the surface, replenish qi and nourish blood, which is conducive to the early recovery of surgical trauma; long-term use of traditional Chinese medicine to support and cultivate the root cause of the tumor, activate blood circulation and eliminate blood stasis, which can be expected to prevent and treat tumor recurrence and metastasis or slow down the tumor metastasis. The combination of Chinese medicine with radiotherapy, chemotherapy and immunotherapy can improve the overall efficacy and alleviate the adverse reactions such as low immunity brought by radiotherapy and chemotherapy. TCM treatment can also be used for patients who are not suitable for surgery, radiotherapy and chemotherapy. Dialectical treatment according to the principles of clearing heat and removing toxins, softening and dispersing knots, etc. can often achieve the purpose of reducing symptoms, improving the quality of survival and prolonging life.
