1.Classical standard radical surgery and modified radical surgery for breast cancer: done by professional team, shortening the operation time and hospital days, reducing complications and improving prognosis; 2.Breast-conserving surgery for breast cancer: curing the disease while preserving the aesthetic appearance of the body, with a breast-conserving rate of 60%; Lu Jianguo, Department of General Surgery, Tangdu Hospital, Fourth Military Medical University 3.Sentinel lymph node biopsy for breast cancer: deciding whether to perform axillary lymph node dissection according to the results of sentinel lymph node biopsy Breast ductoscopy: Through the ultra-fine fiber lens, the fiber ductoscope can penetrate into the breast ducts and diagnose the lesions in the breast ducts at an early stage; 5. 6.Breast reconstruction in one or two stages: implantation of prosthesis, flap formation of latissimus dorsi, flap formation of rectus abdominis; 7.For microscopic breast lesions, which are difficult to locate surgically, a localization needle is placed under the guidance of X-ray or B ultrasound, and then the localization needle and the lesion mass are removed for biopsy at the same time, which greatly improves the diagnosis rate of early breast cancer 8. Keeping up with the new progress in the development of breast specialty, we have improved the standardized surgery and precise clinicopathological staging of breast cancer after surgery, so that breast cancer patients can receive individualized treatment and avoid under-treatment or over-treatment caused by empirical treatment; 9. For certain breast cancers with late staging, we have carried out neoadjuvant treatment before surgery, which creates favorable conditions for radical surgery or breast-conserving surgery with satisfactory clinical results 10. In terms of adjuvant treatment for breast cancer, from the past when chemotherapy was the main treatment, it has developed to a situation where multiple adjuvant treatments including chemotherapy, radiotherapy, endocrine therapy and biological therapy coexist, and the treatment plan is more humanized, and individualized treatment plans can be chosen for different patients with different conditions. After our unremitting efforts, the 5-year survival rate of early-stage breast cancer can reach over 90%, and the 5-year survival rate of mid- to late-stage breast cancer can reach 70-80%; 11. We have established a database of serological, histological and clinical follow-up results of more than 600 breast cancer patients, which has laid a good foundation for clinical basic research work.
