Since the establishment of the Breast Surgery Department of Nanhai Maternal and Child Health Hospital, the hospital leadership has attached great importance to the development of the department, and given strong support in the introduction of talents, investment in equipment and policy guidance, which has led to rapid growth in recent years. In recent years, the business of breast surgery in Nanhai Maternal and Child Health Hospital has been expanding. In benign breast diseases, lesions in the subclinical stage (i.e. not felt and not palpable) are regularly followed up and monitored; lesions with biopsy indications are biopsied with ultrasound or molybdenum targeting in three dimensions to clarify the nature of the lesion. Because of the orientation of the hospital, our department is in contact with a large number of women of childbearing age. lesions, we still put the beauty and health of the breast at heart, so we try to minimize leaving obvious scars on the surface of the breast when dealing with benign breast diseases. Through certain technical means, we try to make the scars hidden and reduced without affecting the treatment effect. We carry out ultrasound-guided breast Encor vacuum-assisted biopsy, minimally invasive duct placement and drainage of breast abscess, and small incision-assisted Encor vacuum-assisted excision of breast (huge) tumors. Through the enhancement of technical means, treatment and beauty can be balanced. Smaller benign tumors are treated by Encor vacuum-assisted surgery with only one tiny incision on one side of the breast, even if there are 7-8 lesions on one side, no additional incisions are required. Most incisions utilize the physiological folds and are well concealed, making scars imperceptible. For acute breast abscesses commonly seen in women of childbearing age during lactation, we have performed minimally invasive surgery with reference to the relevant literature and treated them with an internal duct in the abscess cavity and postoperative irrigation to allow effective drainage of the fibrin and associated inflammatory factors exuding from the inflammation. As observed retrospectively by our department, not only is the minimally invasive surgery wound small and concealed in location, but the healing time is shorter than that of traditional surgical methods and the efficacy is better than that of open surgery. The general minimally invasive resection of benign breast tumors is limited to tumors below 3 cm. After reviewing the literature, our department carried out small incision assisted Encor vacuum assisted resection of breast (giant) tumors, which enabled complete resection of some benign tumors above 4 cm with small incisions. In our previous cases, the largest diameter was 9 cm, and the surgery was completed with a small incision of only 1.5-2 cm. We have made technical progress by improving our surgical methods. We treat each surgical patient seriously, study the surgical plan from various aspects, seek the most suitable treatment plan for “this one” patient, and win the patient’s satisfaction through individualized treatment. For local patients with displacement, intra-glandular infiltration, infection, etc., which are more common after injectable breast augmentation, we treat them differently after detailed examination: for some patients who still have limited gel injection and no obvious scattered infiltration, we also perform minimally invasive surgery to remove the gel and reduce the trouble of surgical scars. For patients with long-term irritation forming multiple granulomas that are not suitable for minimally invasive surgery, we performed excision of the entire gel and the outer encapsulated cystic cavity to reduce the risk of gel residue and postoperative recurrence. For non-lactating mastitis, which is difficult to deal with, the industry has paid much attention to it in recent years because it is recurrent, difficult to cure, and is an autoimmune systemic pathology. In our clinical work, we have received many patients with recurrent ulcers after long-term treatment, and even treated a patient with severe systemic reactions and wheelchair-bound lesions in the breast and extremities, and achieved good results after conservative, minimally invasive or open surgical treatment according to different conditions. For breast malignant tumors, we have comprehensively carried out breast cancer screening, diagnosis, treatment, post-treatment review and relief treatment. Our department has admitted various types of patients in recent years, including Paget`s disease of the breast, ductal carcinoma in situ of the breast, malignant lobular tumor of the breast, mucinous carcinoma of the breast, invasive ductal carcinoma of the breast, invasive lobular carcinoma of the breast, and primary malignant lymphoma of the breast. We have carried out hollow needle aspiration biopsy of breast lesions, ultrasound-guided vacuum-assisted biopsy, and were the first in the province to introduce and carry out fluorescence pulsed ductography-guided sentinel lymph node biopsy and vacuum-assisted biopsy of molybdenum targeting three-dimensional localization of calcified lesions. All medical and nursing staffs of our department have attended many academic conferences and trainings both inside and outside the province, and earnestly study and implement the guidelines and norms for breast cancer diagnosis and treatment of the Chinese Anti-Cancer Association and the NCCN (National Comprehensive Cancer Network) guidelines for breast cancer treatment in clinical work. The treatment plan is individualized according to the different pathological types, early and late stages of the disease (TNM stage) and molecular typing of each patient, and includes neoadjuvant chemotherapy, simple subcutaneous excision of the breast, breast (and/or axillary) conserving radical surgery, modified radical surgery, traditional radical surgery and reconstructive surgery for breast cancer. We do not treat any patient in a simple and hasty manner, but put ourselves in the patient’s shoes and analyze various issues, such as whether the breast can be preserved, whether the axilla can be preserved, and whether breast reconstruction can be performed, while complying with the treatment principles. We try to provide more than two treatment options for the patient to choose from. In our work, before surgery for suspected cancer, each pre-surgical conversation will not be less than 30 minutes, and pathology reports and chemotherapy regimens will be shared with the family in detail. Instead of being a single doctor, we play the role of a counsellor, explaining and analyzing the pros and cons of various options, and fighting cancer together with patients and their families. As a member of the people of Nanhai, being in a rich and developed area, it has always been our goal to improve our practice and provide the local people with quality medical services that are in line with the level of economic development. After many efforts, our Breast Surgery Department has reached the standard of Guangdong Provincial Maternal and Child Health Hospital Breast Disease Prevention and Treatment Center and has the honor to be the Nanhai Branch Center in Foshan. The establishment of the sub-center has ensured the close contact with the provincial maternal and child breast disease prevention and treatment center, which is conducive to the improvement of the department’s business level and the learning and application of new technologies. Guangdong Maternal and Child Health Hospital Sub-center is a multidisciplinary collaborative treatment center with breast surgery as the main body, combined with pathology, imaging and physical examination center. Under the leadership of Prof. Wang Chip and Prof. Zhang Anqin, the center has made remarkable achievements in the standardization of breast cancer screening and early diagnosis techniques and the diagnosis and treatment of non-lactating mastitis, and is undisputedly a leader in the national maternal and child health care system. Professor Wang Chip is a member of the expert group of the Diagnostic Standards for Breast Cancer issued by the Chinese Ministry of Health, and Guangdong Maternal and Child Health Center is the drafting unit of this ministerial standard. The center has been holding national and provincial breast disease study classes and academic conferences every year for many years, which has a great impact. As its sub-center, we will be inspected, supervised and guided by the provincial women and children, and carry out breast cancer screening in the region strictly according to the requirements of the provincial women and children, and input the data into the database uniformly; standardize the monitoring of high-risk groups and post-operative follow-up of breast cancer patients; facilitate the organization of consultation and referral of difficult cases; carry out publicity and education on secondary prevention of breast cancer; accept the supervision and inspection of the provincial women and children breast center once a year; the provincial women and children are responsible for Supervising the standardized treatment of breast surgery in our hospital and guiding the development of new technology and new business. To improve the professional technical level and service awareness of the specialty, so that local women can enjoy high level professional medical services at their doorstep.
