What is BIRAD 3?

Published in BI-RADS Classification 2 mins read

BI-RADS 3 indicates a breast imaging finding that is most likely benign but requires follow-up. In other words, it is a finding that is not expected to be cancerous.

Understanding BI-RADS 3

A BI-RADS (Breast Imaging-Reporting and Data System) score of 3 means that a finding on a mammogram, ultrasound, or MRI is probably benign. However, because there is a small chance (0-2%) that it could be cancer, a follow-up is recommended to monitor for any changes. This approach helps to avoid unnecessary biopsies while ensuring that any potential cancer is detected early.

Key Characteristics of BI-RADS 3

  • Likely Benign: The finding is highly suggestive of being non-cancerous.
  • Low Malignancy Risk: There's a 0-2% risk of the finding being cancerous.
  • Follow-Up Recommended: Close monitoring through repeat imaging is necessary to confirm stability.

Why Follow-Up is Important

Follow-up imaging, typically in 6 months, allows radiologists to assess whether the finding has changed.

What to Expect During Follow-Up

  • Repeat Imaging: You will likely have another mammogram, ultrasound, or MRI.
  • Comparison: The new images will be compared to the original to look for changes.
  • Resolution: If the finding remains stable or disappears, it confirms the benign nature.
  • Upgrade: If the finding changes or becomes more suspicious, the BI-RADS category may be upgraded, possibly leading to a biopsy recommendation.

Examples of Findings Categorized as BI-RADS 3

While specific examples depend on the imaging modality (mammogram, ultrasound, MRI), common scenarios include:

  • Small, well-defined cysts.
  • Solid masses with sharply defined borders.
  • Possibly grouped round microcalcifications.

It's crucial to discuss your individual BI-RADS assessment with your doctor to understand the specific findings and the recommended follow-up plan.
