Breast cancer surgery has evolved from small to large, and has been completed from local excision → radical resection → extended radical resection → modified radical resection that preserves the pectoralis major and/or minor muscles. form change. Relevant experts have found that with the expansion of the scope of surgery, the postoperative survival rate of patients has not significantly improved. At the same time, comprehensive treatment based on surgery can significantly improve the survival rate of breast cancer patients. As a result, breast-conserving surgery came into being, and the surgical treatment of breast cancer entered the era of breast-conserving surgery.

In the past, whether it was the classic surgery for breast cancer treatment, or extended radical mastectomy and modified radical mastectomy, breast removal was a heavy price to pay while treating breast cancer. Postoperative surgery leaves long, ugly scars on women’s chests (patients may have to choose another breast reconstruction surgery after radical surgery). This permanent pain makes many female patients feel that they have lost their dignity as women. and self-confidence, some even feel shameless. In addition, extensive mastectomy and axillary lymph node dissection inevitably bring about many surgical complications. Common ones include: postoperative scar tissue formation, which limits the range of movement of the upper limbs; lymphatic drainage and circulation disorders in the upper limbs, resulting in Swelling of the upper limbs; due to the long surgical incision and extensive subcutaneous dissection, postoperative subcutaneous fluid accumulation or skin necrosis may occur.

Breast-conserving surgery has the characteristics of less trauma and less pain. It retains the integrity of the breast shape while taking into account the functional recovery after surgery. Combined with postoperative comprehensive treatment, the curative effect can be equivalent to the radical cure of breast cancer. Techniques are comparable.
