Breast cancer is a systemic disease. The extent of surgical resection of early-stage breast cancer has little impact on the patient’s prognosis; the principle of modern tumor treatment is to focus on preserving and improving the patient’s quality of life while undergoing radical cure ( function and appearance), which is reflected in the treatment of breast cancer, that is, the scope of surgical resection tends to be narrowed. The comprehensive treatment of breast-conserving surgery, radiotherapy and chemotherapy for early-stage breast cancer is the same as radical mastectomy or modified radical mastectomy in terms of local and regional control rate and long-term survival rate. Breast-conserving surgery and postoperative comprehensive treatment have become the treatment One of the main methods for early breast cancer.

For women who unfortunately suffer from breast cancer and have to undergo mastectomy, their breasts are a helpless pain. Currently, the incidence of breast cancer ranks second among malignant tumors in women, and there are many breast cancer patients. Breast surgeons have been thinking about and exploring the issue of preserving breasts, which are a symbol of women's confidence, while also reliably removing tumors and reducing metastasis and recurrence. Breast-conserving surgery, which has been developed in recent years, has effectively solved this problem for some patients, and is therefore favored by more and more doctors and patients.
