Application of Single-Port Robot-Assisted Breast-Conserving Surgery Via Axillary Approach for Breast Cancer.

Evaluate the safety,feasibility and quality of life(QoL)of single-port robotic surgery in breast-conserving surgery, compare and analyze the advantages and disadvantages of single-port robotic surgery and open surgery in terms of complications, postoperative complications, perioperative recovery effects, and safety in breast cancer breast-conserving surgery, in order to select a more effective and safe surgical method. Subjects who meet the inclusion criteria will enter the research process, with surgery including SPr-breast-conserving surgery or open-breast-conserving surgery, and the choice of the two surgical methods is based on the patient's financial situation and the availability of equipment;

Inclusion Criteria: 1. The patient himself has very high requirements for beauty, and requires no scar on the chest; 2. No chest surgery and radiotherapy. 3. No contraindications to surgery and anesthesia. 4. Clinical I, stage of early breast cancer and the breast has an appropriate volume, can maintain a good breast shape after surgery. 5. Patients in the clinical period who meet the standard of breast conservation surgery after preoperative treatment. 6. Age: ≥18 years old. Exclusion Criteria: 1. Inflammatory breast cancer. 2. The tumor is extensive and it's difficult to achieve negative margins or an ideal breast - conserving appearance. 3. Diffusely distributed malignant - characteristic calcifications. 4. The margin is positive after local extensive tumor resection, and a negative margin in pathological examination still can't be ensured after re - resection. 5. The patient refuses.
