It is often jokingly said that “one third of cancer patients who die are scared to death.” Although this saying is somewhat exaggerated, it actually reflects the importance of psychological factors for cancer prevention and treatment. Authoritative surveys also show that emotional management is beneficial to cancer treatment and physical and mental recovery. There are more than 200 types of cancer, which are closely related to genetics, underlying diseases, living environment and especially lifestyle. However, there is one point that is often overlooked by people, which is the very important psychological factor! Many cancer patients have bad mood for a long time and encounter a major unexpected event, and they can’t top it at once. I once had a liver cancer patient who kept obsessing over the fact that others owed him more than$200,000 and later found out that he had advanced cancer. Chinese medicine says “anger hurts the liver”, this anger out okay, only afraid to hold in the heart will hurt the liver. Modern behavioral medicine classifies people into four types: A, B, C, and D. These types have nothing to do with blood type. These types are not related to blood type, but closely related to the probability of disease: Type A people have a strong sense of urgency, keen, impatient temperament, prone to cardiovascular disease Tianjin Chest Hospital once a survey of more than 100 cases of heart attack patients found that those who belong to type A behavior accounted for 70 percent… The U.S. Central Institute of Health announced that Type A personality is listed as one of the four major factors of heart disease along with cholesterol, smoking and high blood pressure. Type B people are generally more active, optimistic, jocular, and think about everything without much careerism. They may be seen as lazy, but such people are generally mentally healthy. Type C personality – what is known in psychology as the pleasing personality pattern – is a group of people who are more prone to cancer. This type of person usually does not get angry and makes it a point to make others happy as a reflection of his value. Some people accuse him and scold him, but he will not be tit-for-tat, if he is tit-for-tat, he is not a good person. But will life make him happy in every way? Will he have no temper? No way! But he has been suppressing his emotions, and finally faced with a major event or unexpected event, can not suppress, it will be a burst. To use an analogy, like a garbage bag, everyone has bad emotions, type C personality will usually do this: when there are bad emotions to suppress, like pulling the garbage bag to step on; and then, then step on! But never emptied. Eventually this garbage bag really can not hold, and another pile of large pieces of garbage, the garbage bag may be burst. But type A personality will not, there are bad emotions immediately outburst of temper, and then the garbage bag is emptied. Type C personalities are more than three times more likely to suffer from cancer jinx than the average person. Their characteristics include: excessive suppression of their negative emotions, i.e. not good at expressing or venting emotions such as anxiety, depression, despair, etc., especially often trying to suppress the anger that should be vented; behavioral withdrawal, such as yielding to power or pressure, excessive self-restraint, avoidance of conflicts, accommodation, forbearance, tolerance, dependence, submissiveness, and giving up their hobbies and needs for fear of offending or pleasing others. They are prone to helplessness and hopelessness, often unable to cope with the pressure of life, feeling desperate and isolated. Therefore, for the treatment and prevention of cancer, type C people should be the focus of society, which has been proved by studies in Europe and America. If type C people can be more cheerful, find more channels to vent their feelings, look at everything more openly, and find friends or counselors to pour out their feelings when they encounter big events or unexpected incidents, it is very helpful to cancer treatment and prevention, which is also maintaining basic mental health for the general population. Second, the deep-seated cause of cancer is trailed by psychological factors As a doctor, I often pay attention to psychological mind-body integration research results in the treatment process, make psychological adjustment for patients by learning various psychological techniques, and use various psychological techniques to practice on patients continuously. Through my efforts, I have been able to improve the condition of many patients drastically and improve the quality of survival greatly, which is recognized by more and more patients. Many of the deep roots of cancer are involved in psychological factors. As we can see in our daily life, if a person is in a peaceful state of mind, his body is often healthier. Once there is a psychological imbalance, it is easy to produce functional and then organic changes. Not only cancer, but also benign diseases such as hypertension and diabetes. We rarely see people with intellectual disabilities getting cancer, hypertension and diabetes because they do not know what troubles are. On the contrary, people with higher intelligence are prone to cancer. This verifies from the other side that psychological factors have a great influence on cancer. This is a topic that deserves to be explored in depth and is an area that needs to be discovered and studied urgently. Regarding psychological adjustment, TCM has already gained profound insights in this area, such as anger hurts the liver, thought hurts the spleen, what emotions may cause cancer in the five viscera and six bowels, etc. If we can find the root cause of emotions, we will know how to channel them. If Chinese medicine and psychological counseling can be combined together, it may produce a new leap for cancer prevention and treatment. At present, most people still treat cancer as an organic disease. Although almost all hospitals and physicians have determined that psychological factors have an impact on cancer, most oncology hospitals do not have a special cancer psychological counselor. It is believed that with the change of people’s concept, “cancer psychological rehabilitators” will definitely appear in the future, and if cancer patients or their family members need psychological assistance, they can come to the psychological counselors, which will be very helpful for cancer treatment. The first and foremost thing to do when one has cancer is to calm down the mind. If a person is diagnosed with cancer, he or she will feel devastated, which is devastating to one’s health. Some people may not see it on the surface, but they are afraid inside. This is a situation that requires a counselor. We have found examples of people who were checked out that they had cancer and died within a few days. What if he didn’t know? Instead, he may survive for six months or even longer, or even years! That’s why cancer patients need to especially remember the saying: if you are psychologically desperate, your body will collapse! How to prevent cancer from the psychological level? To learn to avoid getting excited and angry, to vent out negative emotions in time, to learn some knowledge of hypnosis, meditation and meditation, and to keep emotional peace, which is very beneficial to physical health. If you are a person with a repressed personality and encounter a major event or trauma, you should go to friends and relatives or experienced physicians or psychologists for guidance and medical treatment.
