Ultrasound Guided Core Biopsy for Breast

Welcome to AR Diagnostics! We specialize in providing accurate and efficient diagnostic procedures, including ultrasound-guided core breast biopsy. This document will explain what to expect during and after the procedure and provide information on its reliability and potential risks.

Ultrasound-Guided Core Needle Biopsies

An ultrasound-guided core needle biopsy involves using a hollow needle to extract small cylinders, or “cores,” of tissue from a suspicious area in the breast. The procedure is performed under the guidance of ultrasound imaging, which allows for precise targeting of the abnormal area. This method is favored for its ability to provide accurate tissue samples with minimal discomfort to the patient.

Why Ultrasound Guidance?

Ultrasound imaging plays a crucial role in guiding the biopsy needle to the exact location of the abnormality. Unlike other imaging techniques, such as mammography, ultrasound does not use ionizing radiation, making it a safer option for repeated use. It also provides real-time visualization, allowing the physician to monitor the needle’s position and adjust as needed, ensuring accurate sampling.

Key Benefits of Ultrasound-Guided CNB

Minimally Invasive: One of the most significant advantages of ultrasound-guided CNB is its minimally invasive nature. The procedure requires only a small incision, reducing the risk of complications and promoting quicker recovery times.

Accuracy: The real-time imaging provided by ultrasound ensures precise targeting of the abnormal area. This accuracy reduces the likelihood of false negatives and ensures that adequate tissue samples are obtained for reliable diagnosis.

Comfort: Local anesthesia is used to numb the area, minimizing discomfort during the procedure. Most patients report only mild pressure or discomfort, making it a more comfortable option compared to surgical biopsies.

Quick Results: Ultrasound-guided CNB is typically a quick procedure, often completed within 30 minutes. The tissue samples are processed promptly, with results usually available within 24 to 48 hours, allowing for timely diagnosis and treatment planning.

Versatility: This method is suitable for a wide range of breast abnormalities, including lumps, masses, and areas of concern detected through imaging tests. It can be used to sample both palpable and non-palpable lesions, enhancing its diagnostic utility.

The Procedure for Ultrasound Guided Core Niddle Biopsy for Breast

Prior to the core biopsy, our interventional pathologist and team will conduct a physical examination to assess the nature of the breast lesion. Once deemed necessary, an ultrasound will be performed to locate the target area precisely. Local anesthesia will be administered to minimize discomfort, and under ultrasound guidance, a core biopsy needle will be inserted to collect tissue samples for further evaluation. Typically, 2-3 tissue samples (cores) are obtained from the area of concern to ensure accuracy in diagnosis.

Length of the Procedure

The entire ultrasound-guided core biopsy procedure usually takes approximately 30 minutes to complete.

After the Procedure

Following the biopsy, you will be monitored for a brief period, typically 15 to 30 minutes, to ensure there are no immediate complications. Once cleared, you can resume your daily activities with no specific restrictions.

What Next?

After the procedure, our interventional pathologist will begin processing the collected tissue samples immediately in our lab. If necessary for a comprehensive evaluation, additional specialized testing, such as molecular testing or immunohistochemistry, may be performed.

When Will I Get My Results?

A detailed report will typically be ready within 24 to 48 hours. If further specialized testing is necessary, the final report will be provided once those tests are completed.

How Reliable Is This Test?

Ultrasound-guided core biopsies are highly reliable. It allows for accurate diagnosis, aiding in the determination of treatment plans. However, like any diagnostic procedure, there are limitations, and in some cases, additional follow-up or procedures may be recommended.


Ultrasound-guided core biopsy is a minimally invasive procedure with minimal risks. Common complications include temporary bruising or tenderness at the biopsy site. In rare cases, bleeding or infection may occur. It is important to notify your doctor if you experience persistent pain, swelling, fever, or excessive bleeding after the procedure.
