Recently, our general surgery breast group successfully performed “minimally invasive surgery for breast masses”. The procedure is guided by ultrasound, and with the help of Mammotome minimally invasive rotary incision system, a breast lump less than 3cm in diameter can be completely removed through a skin incision of only 0.3cm under local anesthesia, which has the advantages of minimally invasive, quick recovery, almost scarless skin after surgery, and does not affect the appearance of the breast. It has considerable advantages for the removal of breast lumps and multiple breast lumps in young female patients. Breast disease is extremely common in women, and the traditional treatment plan is to remove it surgically once it is detected. This method inevitably leaves surgical incision scars on the breast, which affects the appearance, and residual scars in the surgical area, which affects the postoperative review. The Mammotome minimally invasive rotational excision system can be used to treat breast lesions with excellent cosmetic results, and both patients and doctors are satisfied. The Mammotome is a safe and effective technique for the excision of benign surface masses and biopsy of suspicious surface masses, as well as the localization and biopsy of microcalcifications and abnormal shadows in the breast that are negative to palpation, and it meets the requirements of young women seeking scar-free surgery. In general, Mammotome surgery is preferred as long as there are no contraindications and economic conditions allow. The implementation of localization and biopsy of highly suspicious lumps, tiny calcified foci and abnormal shadows in the breast that are negative to palpation can achieve early detection of malignant tumors and thus achieve a complete cure. This time, the breast specialty group of general surgery successfully carried out this new technology to further improve the level of minimally invasive diagnosis and treatment of breast masses in our hospital, which can provide more quality services for female patients.
