Almost all tumors involve psychological factors, and painful psychology may run through the whole clinical process of tumor diagnosis and treatment. Modern medical research has found that the mental state and immune function of the body play a pivotal role in the development and onset of cancer. A good state of mind is a necessary condition for health, and for cancer patients, this is even more important. If patients face tumor mental breakdown and lose confidence in life, the survival rate will be significantly reduced. Helping patients to establish a good psychological state, overcome fear and anxiety, stay away from loneliness and depression, avoid anger and hatred, build hope and optimism, enhance faith and striving, patients can finally overcome the disease, thus improving the efficacy and quality of life of patients. Hippocrates, a famous ancient Greek doctor who is regarded as the father of medicine, said that “the human spirit is the doctor of disease” because optimism, good emotion and positive mental state can function through the nervous, endocrine and immune systems to kill cancer cells. If you are unfortunate to have cancer, besides taking active treatment, you should also adjust your emotions and face the disease positively and optimistically, so that the initiative of life is in your hands. Doctors should also make the whole treatment plan for patients and tell the whole process of treatment possible to mix the war, so that patients can gain maximum self-confidence. The correct outlook on life of tumor patients should try to choose their happiness in life and follow it, and abandon their worries when they meet it, so that they can be quiet, simple, free of delusions, less distractions, open-minded, indifferent and optimistic, and deal with things “calmly”, so that they can have good “coping ability”. The patient will have a good “ability to cope”. Facing the reality and fully motivating patients, facing the fact that they are suffering from cancer, in fact, the fear of death and disease is a very normal psychology, without this fear is not normal, cancer patients have experienced such a stage in the early stage of the disease, but with the clear diagnosis, we have to accept the fact, from the fear of fear to the state of facing the reality, so that patients can establish a strong “In fact, in recent years, more and more tumor patients have been treated with the help of the treatment of cancer. In fact, in recent years, more and more tumor patients have overcome the disease and recovered their health. The available information proves that with modern medical technology, 1/3 of cancers can be prevented, 1/3 can be cured by early diagnosis, and the other 1/3 can reduce pain and prolong life. Music, which we call the essential vitamin M for life, plays an important role in regulating our spirit and mind. When you are sad, it can help you to release your depression and lift your spirits; when you are tired, it will eliminate your fatigue; when you are irritable, it can calm your emotions and brush away your worries. You can imagine that when you feel uncomfortable due to illness, a soothing and beautiful melody will bring you spiritual pleasure, thus temporarily forgetting the physical discomfort. So you may try to use music to adjust your mood. Imagination therapy can be carried out by yourself under the guidance of your doctor, which is a kind of self-referral therapy, that is, the patient implies certain ideas to himself. For example, imagining how you have beaten the tumor, or suggesting to yourself that the disease is not terrible, and that you are optimistic to be a “healthy person with disease”. This may improve the immune function of the body. The task of cancer rehabilitation organizations is to guide and help patients to recover from cancer in a scientific way. Active participation of patients is needed because oncology patients, unlike other disease groups, will face a lot of stress and are prone to psychological problems, which makes humanistic care more necessary. Participating in activities of cancer rehabilitation organizations and communicating with others to get psychological support and social or other people’s help are irreplaceable by hospital treatment and family warmth. It can be said that participation in activities of rehabilitation organizations is an important element for oncology patients to return to society. In participation, we encourage and support each other, so that each patient can embark on the road to recovery in a healthy and optimistic state of mind. It is important to maintain good interpersonal relationship and social interaction, and consolidate psychological recovery and clinical efficacy.
