Stereotactic localization biopsy is a procedure performed by the radiologist in which tissue
is removed from a breast tumor or mammographic abnormality by a needle utilizing a three-dimensional x-ray to guide the needle.
The minimally invasive procedure requires a tiny skin nick in the patients breast, is sutureless, and minimizes the possibility of scarring or breast disfigurement that may occur with surgical biopsy procedures.
The patient lies face down on a table with a hole in it that allows the breast to hang through. The x-ray machine and maneuverable needle are set up underneath the table. The breast is x-rayed from two different angles, and a computer plots the exact position of the suspicious area. The radiologist positions the biopsy needle, advances it into the lesion, and obtains several tissue samples.
