Breast imaging-reporting and data system (BI-RADS) assessment category 1
Citation, DOI and article data
BI-RADS 1 is one of seven categories from the breast imaging reporting and data system. It is defined as negative and is used when imaging demonstrates:
- no finding is present in an imaging modality (not even a benign finding)
- there is nothing to comment on
- a normal examination
The likelihood of malignancy with a BI-RADS 1 classification is essentially 0% and the recommended management is for the patient to continue with routine mammography screening3.
