Adverse psychological factors are closely related to the development of tumors. The psychological state of tumor patients also has a very important influence on the rehabilitation treatment of tumor. A good state of mind is an important condition for tumor recovery. In clinical medical practice, it has a close relationship with many cancer patients. The psychological state of tumor patients, optimistic approach to life, understanding of tumor rehabilitation indicate that maintaining a good psychological state, optimistic approach to life, understanding the medical knowledge of tumor rehabilitation therapy, correcting bad habits and behaviors, establishing confidence in overcoming the tumor, and actively cooperating with the rehabilitation therapy often achieve good therapeutic effects, which can promote the recovery of the tumor, improve the clinical symptoms, improve the quality of life and prolong the survival period of patients. Clinical psychology research shows that a good psychological state can promote the recovery of tumor patients in many aspects. 1. Positive emotion of tumor patients can make patients actively cooperate with medical personnel to take various kinds of treatment measures, and tolerate the toxic and side effects of certain treatment measures, complete the required course of treatment, so as to improve the therapeutic effect of malignant tumors. 2. Optimism of tumor patients can make patients treat cancer as an incurable disease correctly and believe that cancer can be overcome. In this way, the patient’s emotion and spirit will be organized, the mood will be stable, and he will be full of hope for life, so that he can arrange his life in a reasonable and orderly way, live and work like a normal person, make contribution to the country and society, improve the quality of his own survival, and increase the possibility of long-term control of cancer and even clinical cure. 3. The good psychological state of tumor cases makes the patients emotionally uplifted, and they have the vigorous spirit of fighting with cancer. Such patients can often take the initiative to adopt effective rehabilitation measures such as Guo Lin Xin Qigong and Taijiquan, and persist in them for a long time, rain or shine. Patients with the spirit of fighting hard can take the fluctuation of the disease calmly, feel life in the fight against cancer, create joy of life, and reflect the value of life. These patients often achieve good treatment results. 4. It has been proved by research data that hypothalamus plays an important role in the influence of psychological factors on tumor. Positive emotions of tumor patients can effectively regulate the function of the body’s neuroendocrine system, thus inhibiting or slowing down the development of the tumor, which is conducive to the better performance of all kinds of comprehensive rehabilitation measures and the achievement of good therapeutic effects. 5. Relevant researches have confirmed that emotions can affect the immune function. The good psychological state of tumor patients can also enhance the immune function of the body through the regulation of central nervous system, correct the immune defects of the body, reduce or prevent the immune function inhibition caused by radiotherapy and chemotherapy, improve the anti-tumor immune ability of the body, and promote the recovery of tumor patients. Negative emotions can aggravate the condition of tumor patients. Unhealthy psychological state not only promotes the occurrence of tumor, but also promotes the development of tumor and aggravates the condition of tumor patients, which is harmful and not beneficial to tumor patients. Generally speaking, negative emotions can lead to tumor deterioration in many ways. 1. Negative emotions of tumor patients can make patients not actively take necessary treatment measures, thus delaying or delaying effective anti-tumor comprehensive treatment, losing the early and mid-term favorable treatment time after diagnosis, and leading to rapid development and proliferation of tumors. 2. Negative emotions of tumor patients may make patients not actively cooperate with hospitals and medical personnel, making it difficult for doctors to take effective therapeutic measures, and the reluctantly accepted therapeutic means can not play an effective role. In addition, negative emotion may make the patient drink less, lose weight rapidly due to malnutrition, and even lead to the early occurrence of malignant disease. 3. Negative emotions of tumor patients may make them wrongly think that cancer is incurable, and they will do nothing to let God take care of them and let nature take its course. Patients are unwilling to take effective rehabilitation treatment measures such as traditional Chinese medicine, qigong, Taiji spring sowing, etc. They do not pay attention to the reasonable arrangement of life, losing the precious opportunity of comprehensive systematic treatment and accelerating the development of the disease. 4. Negative emotions of tumor patients can further aggravate the neuroendocrine imbalance that has long existed in the patient’s body and promote the deterioration of the disease. Tumor cells, like embryonic cells, divide and grow in a geometric progression, and it takes a long period of time for a single cancer cell to divide and form a huge lump, and this process is affected by various internal and external factors. Negative emotion of cancer patients directly affects the hypothalamus to regulate the neuroendocrine of the body, which promotes the rapid growth of tumor. 5.The adverse psychological state and nervous emotion of tumor patients can reduce the immune function of the body through the central nervous system, which is manifested as the decrease of phagocytic ability of macrophage, dysfunction of thymus gland, inhibition of antibody production, and further obstacle of the function of self-stabilization and immune surveillance, so as to reduce the anti-tumor ability of the body and promote the rapid development of the tumor.
