Fibroadenoma of the breast is a common and frequent disease in young women and is one of the most common benign tumors of the breast. Its clinical manifestation is that one or more lumps can be found in the breast, with clear borders, smooth surface, good mobility, no pain, no adhesion with skin and pectoralis major muscle, and medium texture. Patients often confuse it with lobular hyperplasia and other diseases, and delay treatment; or consider it benign and neglect treatment. However, although fibroadenoma is a benign breast tumor, it still has the possibility of sarcoma (a low-grade malignant tumor of the breast) and may increase rapidly during pregnancy due to elevated hormone levels, so it should still receive sufficient attention from patients. Once formed, fibroadenomas often cannot be removed by medication, massage, or topical application, and surgery is currently the only treatment option for them. Traditional open surgery can leave significant scars on the surface of the breast, which can affect the aesthetics. The application of the mammotome minimally invasive rotary excision system (commonly referred to as minimally invasive surgery), on the other hand, provides complete clarity of the lesion while keeping the appearance of the breast intact to the greatest extent possible. The basic principle of its work can be understood in three simple steps: locating the lump under ultrasound, removing the lump several times with the rotary cutter, and aspirating the specimen several times with vacuum suction. Its greatest advantage is that it provides complete clarity of the lesion while keeping the appearance of the breast intact to the greatest extent possible. At the same time, the postoperative recovery is faster due to the small invasion. Of course, there are always two sides to everything, and it has certain limitations. One, because it is different from open surgery, it cannot stop bleeding by electric knife and ligation under direct vision, but by compression, so in principle, minimally invasive surgery is not recommended for lumps larger than 3 cm in diameter or near the areola; two, because the breast is a substantial organ in which the puncture needle cannot move freely, patients with multiple fibroadenomas often need to choose multiple needle channels or combine them with open surgery. Thirdly, since minimally invasive surgery is to cut the lump small several times and then aspirate it, when a hard lump with calcification is encountered, it may produce what we often call blunt knife phenomenon, which may lead to failure of the surgery and transfer to open surgery; fourthly, since minimally invasive surgery is to cut the lump small several times and then aspirate it, since the specimen is small, usually only postoperative pathology can be done, so it is not recommended to choose this procedure for patients who are older and whose lump may be malignant; fifthly, since it is performed under B-ultrasound, it is not recommended to choose this procedure. Since it is performed under ultrasound, it is often done independently by one surgeon and assisted by other surgeons, so it also requires a high level of operation. Of course, as long as the preoperative preparation is done well and the indications for minimally invasive surgery are strictly mastered, I believe that minimally invasive surgery will bring benefits to the majority of patients, especially young female patients.
