In the past, when breast lump surgery was performed, an incision was routinely made on the surface of the lump, which often left an unsightly scar after surgery. If you have a scar, the scar will continue to grow. This is very difficult for young women who love beauty to accept. With minimally invasive surgery, the surgeon only makes a small incision of 3mm in the hidden area of the patient, inserts the minimally invasive rotary cutter into the breast through the incision, and activates the rotary cutter only after it is close to the lump, cutting off the diseased tissue bit by bit, and the negative pressure suction device simultaneously sucks out the diseased tissue. The procedure takes only 30 minutes. The minimally invasive surgery is very safe, and because of the small incisions, no sutures are required, leaving no scars after surgery and excellent cosmetic results. Patients are observed for one day after surgery and can be discharged the next day with only a band-aid. Since the procedure is a minimally invasive treatment performed under ultrasound guidance, it enables the removal of breast lesions that are clinically inaccessible or difficult to remove surgically. Not only is the external scar small after removal of the breast lump but also the internal scar is small, which has little impact on the diagnosis of further lumps in the breast. It avoids the pain of traditional open surgery and the damage to the shape of the breast, as well as the impact of internal scarring on future examinations and diagnoses.
