Breast biopsy devices that require multiple insertions present a challenge when biopsying small lesions. As samples are acquired with these devices, it becomes more difficult to visualize the area of concern, requiring more time scanning and targeting with each subsequent sample.
When microcalcifications were visible under ultrasound in the past, we were confronted with a difficult decision when wanting to perform an ultrasound-guided biopsy.
This suspicious solid lesion presented a challenging sampling scenario due to its close proximity to the breast implant. With a spring-loaded device, it would have been difficult to obtain samples without fear of damaging the underlying implant capsule.
Sampling of the enlarging solid mass in this patient with a history of left breast cancer and implant reconstruction presented a great challenge due to its very close proximity to the implant and immediately beneath the skin.
Multiple samples of complex cystic masses are often difficult to obtain using a spring-loaded device. If the mass deflates after the initial sample, visualization of the remaining mass becomes difficult, reducing the confidence of sample accuracy.
Posterior masses can be challenging for both ultrasound and stereotactic biopsy due to concerns about their location relative to the patient’s chest wall. The Mammotome® elite™ device provides many benefits in procedures involving lesions near the chest wall.
For years we have performed spring-loaded core biopsy of the axillary lymph nodes when the lymph nodes show evidence of malignant modifications. In general, we have seen good correlation and have recommended lymph node dissection of the axilla.
