Examination Of Benign Breast Tumors

B-ultrasound examination can show the soft tissue structure at all levels of the breast and the shape, size and echo status of the mass. Fibroadenoma mostly presents as circular or oval hypoechoic area, with clear and neat boundaries, uniform internal echo distribution, weak spot, complete posterior wall line, and lateral sound shadow. The echo behind the tumor is enhanced. If there is calcification, the sound shadow may appear behind the calcification point. 2. In mammogram (commonly known as molybdenum target) patients with rich fat in the breast, fibroadenoma shows smooth edges, sharp circular shadows, uniform density, and some can see a thin layer of bright halo around the tumor. A small number of tumors calcify and may be coarse-grained calcifications with flaky or irregular profiles, quite different from the fine grainy calcifications of breast cancer. In the case of dense mammary gland, the tumor and breast tissue density are similar, which can not be clearly shown on X-ray film. Therefore, for young women, due to the relatively dense gland structure of the breast, if there is no special need, molybdenum examination can not be performed. 3. Magnetic resonance examination Magnetic resonance examination cannot replace mammography and ultrasound examination of the breast and corresponding lymphatic drainage area, and the cost is relatively high. However, it can detect lesions that cannot be detected by X-ray and B-ultrasound, and at the same time, it can carry out stereoscopic measurement and functional diagnosis, greatly improving the diagnostic accuracy. 4. Puncture biopsy can be considered when the clinical diagnosis, including imaging examination, is not clear. Fine-needle puncture cytology and hollow needle puncture histology are commonly used. Fine-needle puncture cytology has little trauma and the diagnostic coincidence rate can reach more than 90%. The accuracy of puncture histology with hollow needle was higher. The vacuum-assisted breast biopsy system can perform minimally invasive excision biopsy on small tumors, both in diagnosis and treatment.
