BI-RADS Score (Breast)

Clinical Context & Background

BI-RADS is a standardized system for reporting breast imaging findings (Mammography, Ultrasound, MRI). It classifies findings into categories 0 through 6, each with a specific risk of malignancy and management recommendation.

When To Use

  • Use BI-RADS Score (Breast) when bI-RADS classifies breast imaging findings into risk categories to standardize reporting and guide biopsy or surveillance management decisions.
  • Confirm that the patient, diagnosis, disease phase, and available inputs match the cited model before calculation.

How To Interpret

  • Interpret the displayed result using the calculator-specific formula and reference table, spanning 0 through 6.
  • A boundary result should prompt input verification and clinical review rather than false precision.

What To Do Next

  • Integrate the result with invasive versus in-situ status, stage, receptor biology, treatment timing, genomic testing, comorbidity, and patient goals.
  • Document the inputs, result, timing, and clinical context so the assessment can be reproduced.

Limitations

  • Do not interchange screening-risk, DCIS, invasive prognosis, genomic, and post-neoadjuvant tools.
  • The result supports clinician judgment and does not independently determine treatment.

Frequently Asked Questions

When should BI-RADS Score (Breast) be used?

Use it for patients undergoing breast cancer risk, staging, pathology, recurrence, or treatment-benefit assessment when all required inputs and the intended clinical setting are confirmed.

Can BI-RADS Score (Breast) determine treatment by itself?

No. Interpret the result with the cited evidence, complete clinical assessment, current guidelines, and patient-specific goals.
