Introduction
In 2020, breast cancer replaced lung cancer as the most common cancer in the world, severely affecting women’s health [1]. With the advancement of comprehensive treatment, breast cancer patients have longer survival periods, and the demand for beauty is increasing. More and more patients wish to preserve their breast appearance. In addition, breast resection not only causes physical defects and loss of female image, but also leads to postoperative anxiety and depression[2]. This crisis of confidence may lead to sexual dysfunction, as well as damage to marriage and interpersonal relationships [3]. Therefore, the surgical approach has undergone significant changes. Currently, the surgical approach has changed from the original radical cure by enlargement or improvement to breast cancer radical resection with breast reconstruction while preserving the nipple-areolar complex. Breast-conserving surgery is also a good choice for such patients, but it is not suitable for patients with tumors/breast volumes that are relatively high, with multiple or multiple suspicious cancer lesions or microcalcifications [4]. In addition, most Chinese women have small breast sizes, and most patients have poor symmetry after breast-conserving surgery. Furthermore, postoperative radiotherapy is usually required after breast-conserving surgery. Therefore, most patients currently prefer breast reconstruction surgery. Breast reconstruction surgery for stage I or II breast cancer has emerged as a result. Traditional reconstruction surgery often involves incisions on the surface of the breast, resulting in obvious scarring after surgery. Hoehler [5] first described breast augmentation through the axillary approach in 1973. In recent years, with the development of endoscopic technology, breast cancer radical resection with implant-based reconstruction while preserving the nipple-areolar complex under endoscopic guidance has gradually been mastered by domestic and foreign scholars and has become one of the best choices for early breast cancer patients. The author has improved the current single-port axillary endoscopic breast cancer radical resection and implant patch coverage technique based on previous domestic and foreign surgical methods, achieving good results.
