Several scenarios and symptoms may warrant a recommendation for a breast biopsy.
These include:

• The presence of a palpable lump or mass in the breast.
• Abnormalities are detected through imaging techniques such as mammograms, ultrasounds, or MRIs.
• Changes in breast appearance, such as dimpling or retraction of the skin, nipple discharge, or changes in the nipple’s shape.

It is important to note that not all breast abnormalities indicate cancer. Many benign conditions can mimic cancerous lesions, making a biopsy necessary to differentiate between the two.

Breast biopsies can be performed using different techniques, each with unique intent. Let’s explore the various types of breast biopsies commonly employed:

Fine Needle Aspiration (FNA) is a minimally invasive procedure to collect cellular material from breast lumps or masses. A thin needle is inserted into the lump during an FNA biopsy, and cells are aspirated for examination. This technique is instrumental in diagnosing cysts and benign tumours or determining if a lump is fluid-filled or solid.

The advantages of FNA include its simplicity, relatively low cost, and minimal discomfort. However, in some cases, FNA may yield inconclusive results, as it provides a small sample size for analysis. It may provide a false sense of security. Hence FNAC of breast lump is condemned. It is better to go ahead with a core biopsy, which is discussed ahead. In cases of breast cancer, the role of FNAC is reserved only for suspicious axillary nodes.

Ultrasound-guided biopsies are performed when abnormalities are visible on ultrasound scans but not easily palpable. During this procedure, ultrasound imaging is used to guide the needle to the precise location of the abnormality, ensuring accurate sampling.

Ultrasound-guided biopsies provide real-time imaging guidance, enhancing the precision of targeting tissue samples. They are instrumental in cases where mammography may be limited, such as in young women with dense breast tissue.

Vacuum-Assisted Biopsy (VAB) is an advanced version of the core needle biopsy technique. It enables the collection of multiple tissue samples in a single procedure, making it helpful in diagnosing microcalcifications and small lesions that may not be visible through imaging alone.

VAB offers several advantages over traditional core needle biopsies. It reduces the need for multiple insertions, minimising patient discomfort and the risk of complications. Additionally, VAB allows for a more comprehensive sampling, increasing the accuracy of diagnosis.

Stereotactic biopsy is a technique used to target non-palpable abnormalities detected through mammograms. It uses computerised imaging guidance to locate the abnormality and precisely obtain tissue samples for analysis.

This technique offers a highly accurate and minimally invasive approach to diagnosing breast abnormalities that cannot be felt during a physical examination. Stereotactic biopsy reduces the need for surgical procedures and enables early detection of cancerous lesions.

During an MRI-guided biopsy, a radiologist uses real-time MRI imaging to precisely guide the needle to the abnormal area and collect tissue samples. This technique offers a high level of accuracy, allowing for precise targeting and diagnosis of suspicious lesions.

MRI-guided biopsies are particularly valuable in cases where other imaging techniques have provided inconclusive results or when there is a need to evaluate further abnormalities detected on an MRI scan.

Factors to consider when choosing a biopsy technique include:

• The size and location of the abnormality.
• The presence of microcalcifications or suspicious features.
• The patient’s age, medical history, and overall health.
• The expertise and resources available at the healthcare facility.

It is important to remember that each Biopsy technique has advantages and limitations. The ultimate goal is to obtain accurate diagnostic information while minimising patient discomfort and potential complications.

Breast biopsies are invaluable tools in the diagnosis and treatment of breast abnormalities. By undergoing a biopsy, patients can obtain critical information about the nature of their condition, enabling timely interventions and personalised treatment plans.

Understanding the different types of breast biopsies and their intents empowers patients to have informed discussions with their oncologists. Together, they can make well-informed decisions regarding the most appropriate biopsy technique, leading to accurate diagnosis and improved outcomes.
