Methods Breast cancer patients with early breast cancer were treated by subtotal incision under radical resection of the nipple, and the surface skin of the tumor was removed simultaneously. The latissimus dorsi myocutaneous flap (or latissimus dorsi myocutaneous flap) was used to perform primary breast reconstruction. . Results A total of 10 cases were treated from 1995 to 1997. Six cases were followed up for more than two years and four cases were more than three years. No tumor recurrence or metastasis occurred. The appearance was excellent in 7 cases and good in 3 cases. Conclusions This surgical procedure is simple, minimally invasive, and achieves radical resection of the tumor. The incision is concealed, and the nipple and areola are preserved. The reconstructed breast is beautiful and realistic, and has a good feel. Surgical indications are wider, and can be used for stage I and II breast cancer except for cancer invasion of the nipple, areola or pectoral muscles, skin, etc.
