In the current situation where the incidence of various cancers (i.e. malignant tumors) has increased significantly and the cure rate is relatively low, most patients and their families, including some health care professionals, prefer to look for effective Chinese and Western medicines (including drugs, surgery, radiation therapy, etc.) in order to achieve early cure. Of course, this practice is not wrong, and also has its importance. But only stop here, it is suspected that the prevention and control measures are not one-sided. According to a lot of clinical analysis and personal experience, most people with unbalanced mental health, such as emotionally unstable and narrow personality, have relatively higher incidence of tumor and more unsatisfactory treatment effect or poor prognosis. On the contrary, as long as the prevention and treatment is early, most of the people who are psychologically healthy have better treatment effect and more ideal prognosis. According to the investigation and analysis of personality effects, emotional reactions, life events and psychosocial factors of some clearly diagnosed tumor patients, the results show that: 1. 33-40% of cancer patients have obvious personality anxiety and depression before the disease, and their mental health is out of balance. 2. The personality survey and analysis of patients also showed that the type of neuropsychological imbalance of neuroticism was significantly higher in those who had the disease than in those who did not have cancer, and there were significant control differences. 3. Bad habits or disappointments in life and mental health also often induce or contribute to the occurrence of cancer and affect its treatment effect to some extent. According to some data, more frequent daily life and mental tension, disappointment, fatigue, pessimism, etc., often significantly increase the cancer rate, and the treatment effect is mostly unsatisfactory after getting the disease. In particular, some people are so afraid of cancer that they are afraid of talking about cancer, pessimistic and disappointed, thinking that they have been sentenced to “death”, and they are always anxious and doubtful, so they have already lost the battle mentally and psychologically. Patients with poor mental health like these have poor prognosis; even if they adopt some effective anti-cancer drugs or measures, it is difficult to receive actual results. On the contrary, some people do not have some of the above mentioned mental baggage, have little or no certain negative life events, have a cheerful personality, are emotionally stable and optimistic, and hold the open-minded and optimistic spirit of “if you are here, you are safe, you are not anxious at all, and let your body develop natural resistance”, and with certain medical treatment, you can often receive Some of them can even survive with cancer for more than 30-40 years, and some of them eventually die not from the cancer itself but from other diseases, such as diabetes, cardiovascular disease and cerebrovascular accidents. On the one hand, we should despise it strategically, but on the other hand, we should attach importance to it tactically. Especially, we should not be frightened by the oncoming trend of cancer, but should be optimistic and calm in dealing with it, insist on the spirit of optimism, attach importance to the systematic treatment of medicine, and not make up our own mind and believe in ghosts and gods. In particular, we should adjust our psychological posture, to protect the best and remove the worst, to maintain a happy, calm and normal mental state. In addition to consciously adjusting one’s own mentality and personality interests, one can also use qigong, taijiquan and taiji sword to coordinate one’s mental and psychological state, so that the internal and external environment of an individual can be unified and regulated, which is conducive to preventing and fighting diseases and enhancing the efficacy of treatment. Many successful experiences show that although cancer itself has its own characteristics, it is not absolutely terrible or incurable.
