Breast lumps are a very common and frequent female breast disease, especially in young women, and about 80% of them are benign. Some patients unintentionally feel it themselves, while others are found by doctors during medical examinations. Because breast lumps can grow and become cancerous or sarcomatous, they should be surgically removed when found. In addition, fluctuating hormone levels in women’s bodies during pregnancy can cause fibroadenomas to increase rapidly, so they should also be surgically removed immediately if found before or after pregnancy. However, some patients are reluctant to operate when a mass is found. Some patients do not pay attention to it, some are afraid of surgery, some think it will come back after surgery (this is a wrong view, whether the lump is operated or not does not affect the lump’s regrowth in the future), and some feel that the scars on the breast after surgery affect the aesthetics. The traditional surgical approach does leave visible scars on the breast, and in the case of multiple lumps or scarred patients, the post-operative surgical scars are very visible, and this brings about problems such as painful incisions, scar growth, and breast deformation. Currently, there is a new surgical procedure that has been successfully applied to the removal of breast lumps, which is the vacuum-assisted Mammotome Biopsy System (Mammotome System), a type of minimally invasive surgery that is often referred to. The Mammotome System was founded in 1994 and is based on the core biopsy technique guided by the principle of fine needle aspiration cytology. The system consists of two major devices, the rotary cutter and the vacuum suction pump, which allow complete removal of smaller masses with only 2-3 mm skin incisions, avoiding open surgery and postoperative skin scars. The appearance of the breast is unaffected, reflecting a humane approach, in line with the requirements of minimally invasive surgery, and with few complications. For small breast lumps that are detected by color Doppler but negative to clinical palpation, conventional surgery is difficult to locate and may result in missed or mistaken incisions. The ultrasound-guided excision of small breast masses with negative clinical palpation is difficult to locate and may result in missed or mistaken excision, while the ultrasound-guided excision is accurate and complete, and a clear pathological diagnosis can be obtained, which is highly efficient, minimally invasive, cosmetic and safe.
