Surgery is the best way to treat benign breast lumps, which are the most common lesions in the breast and are most likely to occur in young women between the ages of 20 and 25. However, traditional open surgery inevitably leaves scarring, which affects the aesthetics of the breast, especially in the case of multiple breast lumps, and the surgical scar is a lingering psychological trauma for women who love beauty. Minimally invasive surgery for breast lumps is very popular among women who love beauty, because it is minimally invasive, cosmetic and fast. At present, there are two types of minimally invasive mastectomy for benign breast lumps, one is breast lump rotation and the other is ultrasound-focused Hefei knife. The ultrasound-guided breast lump rotation surgery is highly adaptable and can complete the removal of multiple lumps with a single incision, and the surgical incision is only about 2 mm, which does not affect the appearance of the breast after surgery, and the excised tissue can be examined by postoperative pathology. Therefore, breast lump rotation surgery can also be used for tissue biopsy. However, for larger lumps or or multiple consecutive lumps removed in the same quadrant, there is a possibility of postoperative larger hematoma formation or tumor remnants. The treatment principle of HEFL knife is to gather low energy ultrasonic waves (no radiation) through human tissues, and the focal point in tumor tissues to produce high temperature of 70℃–100℃ to cause instant coagulation necrosis of tumor tissues and achieve the purpose of local necrosis of tumor in vitro without surgery, and the necrotic tumor tissues are gradually dissolved and absorbed by the body, and finally completely absorbed and disappeared without destroying normal tissues other than tumor. It will not damage normal tissues other than tumor and will not hurt breast ducts, which is a green treatment method without surgery and radiation. However, it cannot be used for histopathological examination, so it is only applicable to the removal of benign tumors.
