Traditional Chinese medicine traditionally attaches great importance to the relationship between emotion and disease, and refers to the seven emotions (joy, anger, worry, thought, grief, fear, and fright) and the five wills (joy, anger, worry, thought, and fear) together as “emotion and will” to refer to human emotions and emotional activities in general, and believes that internal injury to emotion and will is one of the causes of disease, often attributed to “yu “cause disease. Zhu Danxi, a famous medical doctor in the Jin-Yuan period, believed that “if the qi and blood are in harmony, all diseases will not arise; if there is a whisker of depression, all diseases will be born, so most of the diseases of human beings are born of depression. The same is true for breast cancer, emotional factors are often an important cause of the disease. Breast cancer is called “breast rock” in ancient times. When the disease is advanced, the lesion is as hard as rock, so it is named breast rock. This has been deeply recognized by many Chinese medical writings, and it is mainly believed that bad emotions, such as depression, anxiety, anger, sadness, etc., if stimulated for a long time, will easily affect the smooth flow of meridians and lead to the malfunction of qi and blood, and furthermore, breast cancer will easily develop. Why is there such a close relationship between emotional activities and breast cancer? According to Chinese medicine, emotional and spiritual activities depend mainly on qi and blood, as described in the Nei Jing, “Blood and qi are the gods of human beings” and “When blood and veins are in harmony, the spirit will live”. In Chinese medicine, women are considered to be “blood-based and qi-based”, meaning that “blood” is the root of women’s physiological activities and “qi” is the driving force of women’s physiological activities, so it is especially important for women to have normal qi and blood functions. Therefore, the normal function of Qi and Blood is especially important for women. If the function of qi and blood is abnormal, the physiological material basis for emotional activities will be lost, which will lead to emotional disorders and emotional diseases. After the development of emotional diseases, in turn, will further aggravate the function of both Qi and blood, the first see Qi dysregulation, manifested as people often say “liver qi stagnation”, Chinese medicine said that the “liver” is very important to regulate the physiological function of the breast, once this regulation can not Once this regulation is not carried out normally, breast cancer will easily occur in the long run. Modern medicine also says that “bad emotions may be the promoter of cancer cells”, and its influence is very complicated. etc.), alteration of DNA structure (enhanced DNA damage, weakened repair, decreased telomerase length and activity, etc.), alteration of immune function (both cellular and humoral immunity) and vascular endothelial growth factor production, ultimately leading to poor lifestyle, DNA alteration, tumor phenotype alteration, tumor angiogenesis and metastasis. The relationship between internal injury of emotion and breast cancer can be described as mutual causation and vicious circle. Emotional trauma can cause breast cancer, and in turn, breast cancer can also cause or further aggravate emotional trauma. Numerous studies have shown that about two-thirds of breast cancer patients suffer from depression or anxiety, as well as decreased sleep quality, and about 10-20% of patients have severe fatigue, which is more pronounced in younger patients and those with more combined medications. Some studies have analyzed the factors affecting the mood of breast cancer patients in different disease stages and concluded that the factors influencing the diagnosis stage are mainly high education, low age and severe disease; the surgery stage is mainly caused by surgery, with an incidence of 15%-60%; the radiotherapy stage is mostly caused by adverse drug reactions; the recovery stage has an important influence of family and social relationships; other factors include: endocrine therapy (menopausal syndrome-like Other factors include: endocrine therapy (menopausal syndrome-like performance), genetics, etc. Chinese medicine attaches great importance to the regulation of the emotions of breast cancer patients. It often starts with regulating qi and blood, using various means such as draining the liver, regulating qi, strengthening the spleen, nourishing the heart, calming the mind, and nourishing the will, and coupled with certain psychological counseling, can often achieve better results. On the one hand, it can improve patients’ sleep quality, and on the other hand, it can relieve patients’ tension, anxiety and depression, so that they can be optimistic about their condition and actively cooperate with the treatment, which is conducive to the recovery of breast cancer, overcoming the disease and actively returning to normal work, life and social activities.
