Vacuum-assisted Biopsy

Vacuum-assisted Biopsy procedures uses stereotactic mammography or ultrasound Imaging. VA biopsy method is a minimally invasive procedure that allows for the removal of multiple tissue samples. 

The special biopsy probe used is inserted and properly positioned, by which a vacuum draws the breast tissue through the aperture of the probe into the sampling chamber of the device. The tissue inside the sampling chamber is collected by the rotating cutting device. Once the tissue sample is captured in the probe the surgeon rotates the thumbwheel of the probe, moving the sampling chamber approximately 30 degrees. 

When sufficient number of tissue samples has been collected the surgeon removes the probe and applies pressure to the biopsy site. An adhesive bandage is applied to the skin nick. 

This method is becoming more common as it is minimally invasive with appearance of no significant scaring. The test procedure can be performed under local anesthesia with the procedure taking less than one hour.
