The incidence of breast cancer is increasing year by year and the age of patients is getting younger. The loss of breast cancer often causes great physical and mental trauma to patients, resulting in low self-esteem, depression and other negative emotions. Breast reconstruction surgery can make up for this defect, and its advantage is that it can meet patients’ psychological needs, and at the same time, it can make the skin more conducive to the plasticity of slight breast sagging after breast reconstruction surgery, and the shape of the reconstructed breast will be better, and through breast reconstruction, it can relieve patients’ psychological pain and bring physical beauty and improve the quality of life, and it will not delay adjuvant radiotherapy and chemotherapy or increase local recurrence. Breast reconstruction surgery is divided into immediate reconstruction and delayed reconstruction, also called stage I reconstruction and stage II reconstruction, in terms of time stage. Phase I reconstruction is the reconstruction of the breast immediately after radical breast cancer surgery, which is performed at the same time as surgical treatment, so that there will be no experience of missing breast and no mental depression caused by physical defects, and reduces the time and cost of secondary hospitalization. Second-stage reconstruction is breast reconstruction performed some time after radical breast cancer surgery. Patients who have experienced the pain of missing breasts should be fully prepared psychologically and physically for the reconstruction surgery. In conclusion, breast reconstruction can not only restore the beauty of women’s body curves but also repair the trauma of women’s heart after it is performed.
