During the development and treatment of tumor itself, some patients will develop some kind of psychiatric syndrome, called tumor psychiatric syndrome, and most of these symptoms have the influence of psychological and social factors, such as anxiety brought by disease, pain brought by treatment measures, fear of death, and concern for family. These psychological factors should be analyzed clinically and relative measures should be taken. Psychosomatic medical theory of oncology Cancer patients often have certain character defects and other predisposing qualities. Many data prove that most cancer patients have the following basic character traits: habitual self-restraint, emotional suppression, good patience, thoughtfulness, introversion and instability. People with such character defects, under the condition of long-term emotional suppression and mental stress, have excessive tension in the central nervous system and limbic system of the brain, which leads to unsynchronized mechanisms, degrades the thymus gland through steroid action, affects the maturation of T-lymphocytes and decreases the production of cellular antibodies, which not only weakens the immune function, but also easily causes the exocytosis of genetic program errors and increases the sensitivity of human body to cancer-causing factors. Adverse psychosocial factors have a pro-cancer effect. Many sources believe that depression, disappointment and unresolved sadness are precursors of cancer. Bad emotions may be the activator of cancer. Bad emotions caused by psychosocial tension stimulation can reduce and inhibit the immune ability of the body, weaken the surveillance role of the immune system in identifying and clearing malignant cells, thus allowing malignant cell lines to proliferate. Cancer patients often present different psychological reactions to illness and emotional disorders centered on mental states. Cancer patients often develop endless fears and thoughts, and a few patients go through roughly six different periods of psychological changes from the beginning to the end of the disease; i.e., experience, doubt, fear, fantasy, despair, and rebounding calm. The emotional and psychological disorders of cancer patients have a significant impact on the treatment and prognosis of the disease. If patients are emotionally optimistic, actively cooperate with treatment and can correctly understand the disease, they can prolong the survival period and improve the quality of survival, otherwise, vice versa. Qigong and psychotherapy put patients in a benign functional state of optimism and clarity, with a significant reduction in channel gas volume, lower arterial oxygen partial pressure, full coordination and unification of the cerebral cortex and limbic system and a high degree of orderliness, and improved electrical energy and electromagnetic efficiency of various organs and systems. Through feedback mechanism, it promotes intracellular mitochondrial proliferation, normal differentiation and growth of cells, enhances systemic immune function, and makes the disease develop in a favorable direction. Psychological care for cancer patients 1. Psychological care when determining cancer diagnosis Since cancer is still a painful chronic disease with poor prognosis, patients are often overly anxious in the process of receiving diagnosis, but they hold the hope that it is better not to have cancer. Doctors should not reveal to patients and their relatives that “it may be cancer” or give out suggestive expressions until they are sure. When the diagnosis is clear but the patient is not mentally prepared, the doctor should give the patient a psychological cushion to avoid too much psychological stimulation, and let the patient build up hope and confidence to cure the disease while knowing that he or she has cancer. It is inappropriate to conceal the cancer diagnosis from the patient or to tell him/her a false diagnosis. Once the patient finds out that he/she has been kept in the dark, he/she will receive a sudden mental shock and will have different degrees of distrust towards the doctor and family members, which is detrimental to the implementation of further treatment measures. Nurses should influence patients with their optimistic attitude towards cancer, so that they will have confidence in the upcoming treatment and hope for their future life. 2. Psychological care during the treatment stage of the disease A perfect treatment plan will enable the patient to recover from the psychological trauma suffered at the time of determining the diagnosis more quickly and bring hope for restoring health and help improve mood. Whether it is chemotherapy, radiotherapy or surgical resection, cancer patients always have to endure great mental and physical damage for a long time. Therefore, doctors must obtain a high degree of trust and close cooperation from patients in treatment, and must explain the whole plan and its advantages and disadvantages as well as treatment measures clearly to patients so that they can be more fully prepared psychologically. If the patient is prepared for the treatment plan, it is easier to accept the side effects of the treatment process. In case of serious treatment reactions, which are more serious than the patient’s imagination, the patient needs both psychological and allopathic support. Patients’ anxiety and anxiety. This kind of psychological support will make the patient emotionally stable and optimistic, which will help to reduce the treatment reaction and make the treatment plan complete successfully. 3.Psychological care for patients with advanced cancer, before death, there is a considerable period of time during which the patient’s body is severely depleted while he or she is still conscious, and in addition to the physical ordeal, he or she also suffers from the emotional pain of saying goodbye to loved ones. Because each person has different personality characteristics, life experiences, cultural qualities and beliefs, their attitudes toward death are different, among which beliefs are the key factor. This is not only a respect for the patient’s personality, but also the greatest spiritual comfort for his family. Care of cancer patients by their family members 1. Active guidance and confidence building Malignant tumors, due to late detection and various conditions, often lose the chance of radical treatment until they are found to be tumors, and only symptomatic treatment measures can be taken. When many patients hear that they have cancer, they will be pessimistic and fearful and their spiritual pillars will collapse. Therefore, family members should first build up confidence, not to be downhearted all day long, but to learn more about the treatment and nursing experience of cancer patients, so as to overcome cancer together with them. To understand the patient’s temperament and prescribe the right medicine. Some people are emotionally fragile, worried and easily agitated. To such people, we should hide the true feelings and implement protective medical treatment to keep the patient in a relaxed state of mind, so as not to scare the patient before the treatment. For people with high literacy, cheerful and strong character, politely or frankly make the condition clear to obtain the patient’s cooperation, otherwise, due to the psychological sensitivity of multiple consultations and examinations, it will cause suspicion; or by chance the patient knows, but causes depression and aggravation of the patient’s condition. 2.Patient care and tirelessness The systemic symptoms of advanced cancer patients are complex and diverse, and the treatment effect is not obvious, such as pain, fever, bleeding and renal failure. Patients will be dissatisfied with doctors, nurses, hospitals and everything around them under the torture of pain, and this emotion will lead patients to lose their temper with their family members, then it is necessary to patiently adapt to patients, think for them in every way, put in their favor, distract them, make them more happy and think less about the disease, and family members should understand the painful feelings of patients tortured by the disease. 3.Strengthening nutrition and assisting activities Malignant tumor grows unrestrictedly, consuming a lot of energy and protein of the body, causing hypoproteinemia and electrolyte disorder, etc. In addition to the side effects of chemotherapy and radiotherapy on gastrointestinal tract, patients often have nausea, vomiting and no appetite, etc. In this case, we should make some nutritious and easily digestible food according to the appetite of patients and encourage patients to eat more to improve the negative nitrogen balance in the body.
