The working process of this method (Stereotactic Breast Biopsy)
Principle of the Breast Biopsy Device is that once the patient is properly positioned, digital mammography is first performed (which is a fast method and reduces radiation exposure to the breast tissue) to locate the lump that the doctor wants to biopsy for pathological examination using a computer in the x, y, and z axes in 3D. The doctor will determine the position of the lump and automatically move the biopsy needle to the specified location. After that, the doctor will sterilize the patient’s skin, inject local anesthesia, and insert the biopsy needle (ATEC) while suctioning the surrounding tissue with a vacuum system using the ATEC needle and the Suros device. The obtained tissue is then sent for pathological examination. This process takes about 30-60 minutes. After completion, most patients can go home with minimal pain and a small skin wound.

Advantages of the ATEC Needle Used with the Suros Device

This makes the biopsy process faster than other types of biopsy needles because there is no need to repeatedly withdraw and reinsert the needle to obtain multiple tissue samples. This tool can rotate 360 degrees and can reduce hematoma formation around the wound. If the lump is small, it can be completely suctioned out. This method is slightly more expensive than using other types of needles.

Benefits of Core Needle Biopsy Compared to Open Biopsy

  • Reduces pain during and after surgery
  • Reduces bruising to normal breast tissue
  • Faster recovery
  • Wound size is equal to the needle hole, smaller than general surgery
  • Improves efficiency in planning further treatment
Additionally, Core Needle Biopsy can be used with Ultrasound to help locate the lump. The doctor will decide which method is appropriate and easiest for obtaining the tissue sample.
