BI-RADS categories range from 0 to 6, each indicating a different level of concern and recommended action:
BI-RADS 0: Incomplete - Additional imaging evaluation and/or comparison to prior mammograms is needed. BI-RADS 1: Negative - No signs of malignancy. Routine screening is recommended. BI-RADS 2: Benign - Non-cancerous findings. Routine screening is recommended. BI-RADS 3: Probably Benign - Findings have a high likelihood of being non-cancerous. Short-term follow-up is recommended. BI-RADS 4: Suspicious - Findings are suspicious for malignancy. A biopsy should be considered. BI-RADS 5: Highly Suspicious of Malignancy - High probability of cancer. Appropriate action should be taken. BI-RADS 6: Known Biopsy-Proven Malignancy - Cancer has already been confirmed. Appropriate treatment is necessary.
