When a lump or abnormality is found in the breast, a biopsy is usually performed to determine if it is cancerous. A biopsy involves the removal of tissue from the affected area and examining it under a microscope.

There are several types of breast biopsy, including core needle biopsy, open surgical biopsy, and ultrasound-guided biopsy. One alternative method is stereotactic biopsy, which uses mammography to guide the biopsy needle to the abnormality.

What is Stereotactic Biopsy?

Stereotactic biopsy is a minimally invasive diagnostic procedure that uses mammography to guide the biopsy needle to the area of concern. It is commonly used for non-palpable lesions or lesions that cannot be seen or felt during an examination.

The procedure is performed under local anesthesia, and the patient is awake during the entire process.

The mammogram is used to locate the abnormality, and a computer generates a three-dimensional image of the breast tissue. This allows the radiologist to precisely guide the biopsy needle to the correct area.

The needle removes a small amount of tissue, which is sent to a laboratory for analysis. The results of the biopsy can determine if additional testing or treatment is needed.

Advantages of Stereotactic Biopsy

There are several advantages to stereotactic biopsy. Unlike open surgical biopsy, it is minimally invasive and does not require general anesthesia.

This means that it can be performed as an outpatient procedure, and the patient can return home the same day. The procedure is also more cost-effective than an open surgical biopsy.

Additionally, stereotactic biopsy is very accurate. The three-dimensional mammogram allows the radiologist to precisely locate the area of concern, reducing the risk of missing the abnormality.

The method also allows for multiple biopsies to be taken from one location, reducing the risk of false negatives.

Who is a candidate for Stereotactic Biopsy?

Stereotactic biopsy is recommended for women with breast abnormalities that have been detected through a mammogram or other imaging studies.

It is commonly used for non-palpable lesions, but it can also be used for palpable masses that are difficult to locate. Women who are pregnant or who have bleeding disorders may not be candidates for stereotactic biopsy.

It is important to discuss all treatment options with your healthcare provider to determine the best course of action for your individual case.

Risks of Stereotactic Biopsy

Like any medical procedure, there are some risks associated with stereotactic biopsy. The most common side effect is bruising at the biopsy site, which usually lasts for a few days.

Some patients may also experience mild swelling or discomfort in the breast following the procedure. In rare cases, the biopsy may lead to infection or bleeding.

It is important to discuss all possible risks with your healthcare provider before the procedure to ensure that you fully understand what to expect.

Preparing for Stereotactic Biopsy

If your healthcare provider recommends stereotactic biopsy, there are a few steps you can take to prepare for the procedure. You may be asked to avoid blood-thinning medications, such as aspirin or ibuprofen, for several days before the procedure.

You should also avoid caffeine for 24 hours before the procedure, as it can affect the accuracy of the mammogram.

You may be asked to wear comfortable, loose-fitting clothing on the day of the procedure and to avoid any jewelry or metal objects.

You should also arrange for someone to drive you home after the procedure, as you may experience some discomfort or drowsiness.

After Stereotactic Biopsy

After the procedure, you may experience some mild discomfort or swelling in the breast. You can take over-the-counter pain medications, such as acetaminophen or ibuprofen, to alleviate any discomfort.

You should also avoid strenuous activities and heavy lifting for a few days following the procedure.

The biopsy site should be kept clean and dry, and you should avoid soaking in water or using hot tubs or saunas for at least 24 hours after the procedure. You should also avoid any vigorous activity that may cause the biopsy site to bleed.

Follow-up Care

Your healthcare provider will schedule a follow-up appointment to discuss the results of the biopsy. If the biopsy shows abnormal cells or cancer, your provider will discuss treatment options with you.

If the results are negative, further testing may be recommended to monitor any changes in the area over time. Regular mammograms and breast exams are recommended for all women, regardless of the results of their biopsy.

Conclusion

Stereotactic biopsy is a minimally invasive alternative to open surgical biopsy. It is a highly accurate method for diagnosing breast abnormalities and can be performed as an outpatient procedure.

While there are some risks associated with the procedure, they are typically minor, and the benefits of early detection and treatment far outweigh the risks.
