Breast cancer is one of the most common malignant tumors in women, accounting for 10% of malignant tumors in China, and in some areas (such as Shanghai) has accounted for the first place of female malignant tumors, and the trend is rising rapidly year by year. 2005 incidence rate of breast cancer in Shanghai has 77.7 (per 100,000 cases). The incidence rate of breast cancer in Shanghai is 77.7 (per 100,000 cases) in 2005 and is increasing at the rate of 1.14/100,000 per year. Various epidemiological studies indicate that the low age, urbanization and expansion of breast cancer have taken initial shape in China. In the process of breast cancer diagnosis and treatment, patients not only have the psychological burden of general malignant tumors, but also the great psychological impact caused by the loss of the breast as a very important female sex symbol, whose reaction is sometimes even greater than that of the cancer itself, which affects the whole process of diagnosis, treatment, recovery and follow-up of the disease, and also has a series of serious consequences on the patient’s marriage, family, work and social role, as well as on the psychological impact of the patient’s family members. It also has a series of serious consequences on the patient’s marriage, family, work and social roles, as well as psychological effects on the patient’s family members. Therefore, how to provide psychological interventions in all periods of breast cancer has become an important issue nowadays. Currently, there are more and more patients with early stage and low age breast cancer, and most of them are seen without obvious symptoms and psychological preparation. They show strong denial and panic psychology at the initial clinical diagnosis, as well as the desire to take a chance. Surgery is often regarded as a major event in life, and patients can have strong psychological reactions before, during and after surgery. If not properly recognized and handled, it will not only cause patients pain, but also hinder surgery and postoperative recovery, and even cause physical and mental diseases and sequelae. After puncture and biopsy, when breast cancer patients are diagnosed pathologically, they will have strong psychological reactions, which is called the psychological shock period. It is divided into shock-fear period, denial-doubt period, anger-depression period, and acceptance-adaptation period, which usually lasts 3-7 days. Extroverts are restless, sad and tearful, and even weeping. Introverts are sullen, preoccupied, silent, and extremely depressed. There can be aggression and suicidal tendencies, and excessive deliberate demands on medical care. During this period, protective psychological intervention is needed, i.e., not to rush to correct the patient’s denial psychology in order to ease the sudden heavy blow brought by the information of cancer diagnosis, so that the patient can be prepared for both physical and mental resilience. Positive psychological implication, such as small tumor, early detection and good treatment effect, can be compared with similar patients, implying that she has a good prognosis after active cooperation with treatment. Create a positive atmosphere in the ward to overcome the disease. Patients recovering from surgery in the ward can be invited to give a personal account to eliminate patients’ fear of surgery. Establish a good doctor-patient relationship. The patient’s trust in the surgeon directly affects the outcome of surgery and reduces postoperative adverse psychological reactions. Pre-operative visits by the attending surgeon are an important psychological intervention. Create a good operating room environment and surgical atmosphere, such as the calm demeanor of the medical staff, background music playing in the operating room, and good words and attitudes of the relevant personnel before and after anesthesia.
