The Department of Breast Surgery at Renji Hospital, Shanghai Jiao Tong University School of Medicine, adheres to the philosophy of people-oriented care and attention to detail in providing patients with a favorable medical environment; and upholds the principles of evidence-based standardization and individualized comprehensive treatment in delivering high-quality therapeutic experiences for patients. The department is equipped with internationally advanced digital mammography, ultrasound, stereotactic X-ray localization systems, breast magnetic resonance imaging scanners, vacuum-assisted minimally invasive breast biopsy systems, bedside imaging localization systems, and other specialized diagnostic equipment for breast diseases. These not only provide patients with convenient and efficient services but also bring breast disease diagnosis to an internationally advanced level. The department has pioneered high-quality imaging-guided localization of breast masses (such as MRI-guided localization), significantly increasing the detection rate of early-stage breast cancer and micro-tumors, thereby achieving the goal of precision surgery. The department actively carries out minimally invasive breast biopsy, sentinel lymph node biopsy, breast-conserving radical surgery, modified radical mastectomy, and various breast reconstruction surgeries, providing patients with appropriate individualized surgical treatment. While ensuring therapeutic efficacy, the department places greater emphasis on humanistic care for patients, reducing the psychological trauma caused by breast cancer surgery, enabling patients to better return to society, resume their social roles, and preserve their quality of life to the greatest extent possible. In addition to surgery, the Department of Breast Surgery at Renji Hospital provides comprehensive breast cancer treatment including chemotherapy, radiotherapy, endocrine therapy, and targeted therapy. The department has established a distinctive neoadjuvant chemotherapy diagnostic and treatment system, which has helped a large number of patients with previously inoperable, refractory locally advanced breast cancer achieve tumor downstaging to reach surgical eligibility, while further effectively improving patients' long-term prognosis. The Director of the Department of Breast Surgery at Renji Hospital is Professor Lu Jinsong, a doctoral supervisor who has dedicated over 30 years to the early diagnosis and systemic treatment of breast cancer. He serves as the convener of the Multidisciplinary Team (MDT) for Comprehensive Treatment of Breast Diseases, a council member of the Chinese Society of Clinical Oncology (CSCO), Vice Chairman of the Breast Disease Professional Committee of the China Medical Education Association, Deputy Head of the Breast Cancer Marker Working Group of the Tumor Marker Professional Committee of the Chinese Anti-Cancer Association, a member of the MDT Committee of the Surgical Branch of the Chinese Medical Doctor Association, a member of the Breast Specialty Committee of the Surgical Branch of the Chinese Medical Doctor Association, Vice Chairman of the First Breast Disease Expert Committee of the China Primary Health Care Foundation, a member of the Cardio-Oncology Group of the 11th Committee of the Cardiovascular Disease Branch of the Chinese Medical Association, and a member of the First Committee of the Breast Disease Digital Diagnosis and Treatment Professional Committee of the Digital Medical Technology Branch of the China Medical Equipment Association. He received the title of "Medical Ethics Model" of the Shanghai Education and Health System in 2011 and "Top Ten Doctors" of Shanghai in 2012. He has published more than 60 academic papers internationally, and has guided graduate students in writing 13 papers that were presented at international breast cancer conferences, two of which received the Avon-AACR International Scholar-in-Training Award at the 2012 San Antonio Breast Cancer Symposium, a top international breast cancer forum in the United States. The multidisciplinary diagnosis and treatment team of the Department of Breast Surgery at Renji Hospital relies on the strong talent advantages of multiple disciplines at Renji Hospital, integrating experts from all breast cancer diagnosis and treatment-related departments across the medical field to form a precision MDT team within the broader medical scope of breast cancer, providing precise staging and optimized treatment for difficult and complex cases. With the collaboration of the MDT team, breast cancer patients with concurrent critical illnesses can also receive convenient, scientific, and effective treatment. The Department of Breast Surgery at Renji Hospital has conducted numerous innovative clinical research studies related to breast cancer, establishing advanced treatment models and therapeutic concepts, enabling breast cancer patients to have access to up-to-date, diversified, and individualized diagnostic and treatment plans. The doctors and researchers in the Department of Breast Surgery have always been committed to innovation, forging ahead on the path to improving the survival of breast cancer patients. Currently, some of the department's academic viewpoints have been cited by the U.S. NCCN Clinical Practice Guidelines in Oncology for Breast Cancer for ten consecutive years since 2014 (as of 2024). This is also the first time that the NCCN Breast Cancer Clinical Guidelines have cited viewpoints from papers published by a Chinese clinical research team. The Department of Breast Surgery at Renji Hospital also has a warm and experienced nursing team. With professional breast disease nursing knowledge, they help breast cancer patients recover. While providing patients with convenient and high-quality medical services, the team has also established a WeChat platform to provide health education, postoperative rehabilitation guidance, and psychological counseling through information communication services, allowing the pink ribbon to dance gently in the heart of every woman.
