Untouchable breast lesions are breast lesions that are detected by imaging but cannot be palpated clinically. The probability of a biopsy confirming a malignant lesion is 25% to 30%, and 75% to 85% of them are early stage cancer. Therefore, when no lump is felt, it does not mean that there is no problem with the breast. Adult women still need to insist on regular checkups, and only regular checkups can detect lesions early and get the best treatment time. The common means of localization for non-palpable breast lesions are mammography and ultrasound. We first need to define what kind of lesions should be taken seriously and require surgical biopsy. The mammogram shows small sand-like calcifications with or without masses, irregular hyperdense or structurally disturbed areas, isolated masses, burr-like or lobulated masses, localized glandular border defects or depressions, and ultrasound shows irregular mass borders, crabfoot-like changes, posterior mass attenuation, masses with abundant blood flow, masses with calcifications, thickened cyst walls or hypoechoic cysts, or abundant blood flow around the cyst. The presence of these signs should be suspected. The presence of these signs should be suspected as a malignant lesion, and even if the breast lesion cannot be palpated clinically, it should be promptly removed for biopsy. The Mammotome is a minimally invasive breast surgery system that is safe and effective and has unique advantages that cannot be compared with traditional surgery: 1) precise localization and accurate removal of lesions that cannot be palpated. 2, the incision is only 2-5 mm, cosmetic effect and no stitches, no scars; can remove multiple lesions in one side of the breast through one incision. 3. High-tech design ensures safety and avoids needle transfer of tumor cells. 4. More accurate diagnosis, large and continuous specimens can be obtained, reducing the false-negative rate of pathology. 5.Low infection rate, saving the cost of anti-infection. 6.The operation is fast and convenient, with short operation time and light pain. 7.Entered the medical insurance.
