Stereotactic Surgery

In breast care, the term stereotactic surgery refers to a stereotactic biopsy, a precise technique that uses mammography to pinpoint an abnormality and guide a needle to exactly the right spot. The word stereotactic describes the use of images taken from different angles to calculate the location of a target in three dimensions. This approach is especially valuable for sampling areas that can be seen on a mammogram but not on an ultrasound, such as clusters of microcalcifications. It is frequently combined with vacuum-assisted technology so that an adequate amount of tissue can be obtained through a single small skin opening, allowing an accurate diagnosis without the need for open surgery.

Any blood-thinning medications should be mentioned in advance, as they may need to be paused briefly to lower the risk of bleeding. The procedure is carried out under local anesthetic, so general fasting is usually not required. Because positioning is important for accuracy, it is helpful to wear comfortable clothing and to let the staff know about any difficulty lying still in one position.

For most stereotactic biopsies, the person lies face down on a specialized table with the breast positioned through an opening, although some systems are performed while seated. The breast is gently compressed, and mammographic images are taken from different angles. A computer uses these images to calculate the precise coordinates of the target area. After the skin is numbed, a small nick is made and the biopsy needle is guided to the exact location, where tissue samples are collected. A tiny marker is usually placed to identify the site on future imaging. The procedure generally takes between thirty minutes and an hour.

Stereotactic biopsy is a safe, minimally invasive procedure. The most common after-effects are bruising and mild soreness, along with a small amount of bleeding at the site. Infection is uncommon. Some people find the compression or the need to remain still for a period uncomfortable, but this resolves once the procedure is complete.

Pathology results are compared with the imaging to ensure the findings are consistent. If the result is benign, routine follow-up continues, with the marker assisting future image comparison. If a cancer or a high-risk change is identified, the care team will discuss surgery or other treatment, and the marker helps the surgeon locate the area accurately.
