BI-RADS, or the Breast Imaging Reporting and Data System, is a standardized scoring system used in mammography reports to categorize the findings and assess the likelihood of breast cancer. The system helps radiologists communicate results clearly and consistently. It ranges from category 1 (not cancer) to category 6 (high likelihood of cancer).
Understanding BI-RADS Categories
The BI-RADS system uses a numerical scale with different categories to reflect the findings of mammogram results:
| BI-RADS Category | Description | Recommendation |
|---|---|---|
| 0 | Incomplete. Additional imaging needed. | More tests, such as additional mammogram views, ultrasound or MRI. |
| 1 | Negative. No findings of concern. | Routine screening. |
| 2 | Benign findings. No sign of cancer. | Routine screening. |
| 3 | Probably benign. Short-term follow-up is advised. | Short interval follow-up imaging in 6 months. |
| 4 | Suspicious. Biopsy should be considered. | Biopsy of the suspicious area. |
| 5 | Highly suggestive of malignancy. Biopsy is highly recommended. | Biopsy of the suspicious area. |
| 6 | Proven malignancy. Known cancer. | Treatment and management of cancer. |
Additional Information
-
Breast Density: Mammogram reports also include breast density categories, which impact the interpretation of mammograms as dense tissue can obscure abnormalities.
-
Communication: The BI-RADS system ensures clear communication between radiologists and healthcare providers, facilitating appropriate follow-up care and management.
-
Consistency: The system promotes consistent interpretations of mammograms, reducing variability in diagnosis.
By using the BI-RADS system, healthcare professionals can better evaluate mammogram results, and recommend the best approach for patient care, be that further testing, follow-up, or treatment.
