- BI-RADS 0 Need Additional Imaging Evaluation and/or Prior Mammograms For Comparison:
- BI-RADS 1 Negative: There is nothing to comment on. The breasts are symmetric and no masses, architectural distortion or suspicious calcifications are present.
- BI-RADS 2 Benign Finding:Like BI-RADS 1, this is a normal assessment, but here, the interpreter chooses to describe a benign finding in the mammography report.
1- Involuting calcified fibro adenomas.
2- Multiple secretory calcifications.
3- Vascular calcifications.
4-fat-containing lesions such as oil cysts, lipoma, galactoceles and mixed-density Hamartoma all have characteristically benign appearances, and may be labeled with confidence.
5- Intramammary lymph nodes.
6- Implants.
7- Architectural distortion clearly related to prior surgery.
Radiologist is still concluding that there is no mammographic evidence of malignancy.
-BI-RADS 3 Probably Benign Finding - Initial Short-Interval Follow-Up Suggested:A finding placed in this category should have less than a 2% risk of malignancy.It is not expected to change over the follow-up interval, but the radiologist would prefer to establish its stability.Lesions appropriately placed in this category include:
· 1-Non palpable, circumscribed mass on a baseline mammogram (unless it can be shown to be a cyst, an intramammary lymph node, or another benign finding),
· 2-Focal asymmetry which becomes less dense on spot compression view
· 3-Cluster of punctuate calcifications
BI-RADS 5Highly Suggestive of Malignancy. Appropriate Action Should Be Taken: BI-RADS 5 must be reserved for findings that are classic breast cancers, with a >95% likelihood of malignancy. 1-A speculated, irregular high-density mass
2-a segmental or linear arrangement of fine linear calcifications
3- An irregular speculated mass with associated pleomorphic calcifications.
BI-RADS 5 contain lesions for which one-stage surgical treatment could be considered without preliminary biopsy. However, current oncologic management may require percutaneous tissue sampling as, for example, when sentinel node imaging is included in surgical treatment or when neoadjuvant chemotherapy is administered.
- BI-RADS 6Known Biopsy Proven Malignancy. Appropriate Action Should Be Taken BI-RADS 6 is reserved for lesions identified on the imaging study with biopsy proof of malignancy prior to definitive therapy.This category was added to the classification because sometimes patients are treated with neo-adjuvant chemotherapy. During the course of the treatment the tumor may be less visible, while still you know you are dealing with cancer.
