BIRADS in Mammography: What You Need to Know

• August 20, 2024
• By Fernando Amato

1. 📊 BIRADS is a classification system that standardizes mammography reports and other breast exams.

2. 🩺 There are 7 categories in BIRADS, ranging from inconclusive exam to already diagnosed cancer.

3. 🔍 The BIRADS classification aids in the early detection of breast cancer.

4. 🤝 A report with BIRADS 4 or 5 generally requires a biopsy to confirm or rule out malignancy.

5. 📅 Follow-up with a specialist is essential after obtaining a report with any BIRADS category.

What is it and how to interpret it?

The term BIRADS is widely used in radiology, especially in the context of breast exams, such as mammography. But what exactly does this acronym mean, and how can it impact diagnosis and treatment? In this article, we will explore the BIRADS system, how healthcare professionals use it, and what each category represents.

What is the BIRADS system?

BIRADS is the acronym for Breast Imaging Reporting and Data System, a classification system developed by the American College of Radiology (ACR). It standardizes the reports of breast imaging exams, such as mammography, ultrasound, and magnetic resonance imaging, providing a common language among radiologists and other healthcare professionals.

This system thus aids in the interpretation of exams and helps determine the next steps, whether it is routine follow-up or a more in-depth investigation.

How Does the Classification Work?

It classifies mammographic findings into seven categories, numbered from 0 to 6. Each number, however, corresponds to a level of concern regarding the presence of breast cancer, guiding medical conduct. Below, a detailed explanation of each category:

BIRADS 0: Incomplete Assessment

This category indicates that the examination was inconclusive and additional exams, such as an ultrasound or magnetic resonance imaging, are needed for a complete assessment.

BIRADS 1: Negative Exam

This means that there are no significant changes in the breasts and the breast tissue is normal. In this situation, routine screening is recommended to continue.

BIRADS 2: Benign Findings

In this category, clearly benign changes were observed, such as simple cysts or fibroadenomas. There is no suspicion of cancer, and regular follow-up is recommended.

BIRADS 3: Probably Benign

Findings that have more than a 98% chance of being benign, but still require closer follow-up, usually with exams every 6 months, to ensure there are no significant changes.

BIRADS 4: Suspicious

This category is then subdivided into 4A, 4B, and 4C, indicating different levels of suspicion for malignancy. In this situation, however, a biopsy is often recommended to clarify the nature of the lesion. The chances of it being malignant then range from 2% to 95%, depending on the subcategory.

BIRADS 5: Highly Suggestive of Malignancy

Thus, findings in this category have a high probability (above 95%) of being cancer. Therefore, in this case, a biopsy is practically mandatory to confirm the diagnosis.

BIRADS 6: Known Cancer

This classification, then, is used when a diagnosis of breast cancer has already been confirmed, and the BIRADS system accompanies the response to treatment.

The Importance in Diagnosis

It is, therefore, an essential tool for the early detection of breast cancer, allowing clinical decisions to be made with greater precision. It helps to reduce variability between reports, ensuring that radiological findings are interpreted uniformly and that patients receive appropriate follow-up.

When to Seek a Specialist?

So, if you received a mammography report with this classification, it is important to discuss it with a specialist, such as a plastic surgeon specializing in breast reconstruction or a mastologist. This will ensure that you receive the correct guidance and, if necessary, start treatment early.

Questions and Answers

1. What does BIRADS 0 mean?

It means that the exam was inconclusive and additional exams are needed.

2. What exams may be requested after a BIRADS 0?

Generally, the doctor may request an ultrasound or magnetic resonance imaging for a more detailed evaluation.

3. Is BIRADS 3 a cause for concern?

Although category 3 indicates a very low probability of malignancy, closer follow-up is necessary to monitor for any changes.

4. What to do if I receive a BIRADS 4 report?

If your report indicates 4, the doctor will likely recommend a biopsy to determine if the lesion is malignant.

5. Does BIRADS 5 mean I have cancer?

It indicates a high probability of malignancy, but confirmation can only be made through a biopsy.

6. How is follow-up for a BIRADS 3 done?

Follow-up is generally done with imaging exams every 6 months, for up to two years.

7. Can BIRADS 2 evolve into cancer?

It indicates benign lesions, which do not have the potential to evolve into cancer.

8. Who can interpret a BIRADS report?

The interpretation of the BIRADS report should be done by a radiologist, and discussed with a mastologist or plastic surgeon.

9. What does BIRADS 6 mean?

BIRADS 6 is used when there is already a confirmed diagnosis of breast cancer.

10. How to schedule an appointment to discuss my BIRADS report?

You can schedule an appointment with a specialist in mastology or plastic surgery to discuss your report. In this case, Dr. Fernando Amato is available to assist you.
