BI-RADS II is a benign category in the breast imaging reporting and data system. A finding placed in this category should have essentially a 100% chance of being benign. 

Examples of such lesions include:

Reporting recommendations

Although BI-RADS 1 and BI-RADS 2 have an essentially 0% chance of malignancy, BI-RADS 1 is used in situations where the breast is completely unremarkable, and BI-RADS 2 is used when the radiologist wants to remark on a benign finding.

Any BI-RADS 2 breast finding is not expected to change over the follow-up interval. The radiologist should mention that it is a definite benign lesion.

Usual screening follow-up is recommended.
