  Code	Display
  Category0	Category 0 (Incomplete)	Need additional Imaging Evaluation and/or prior Mammograms for comparison. Recall for additional imaging and/or comparison with prior examination(s) [Breast Imaging Reporting and Data System—Mammography, Fifth Edition] Valid for the following modalities: MG US MRI NM.
  Category2	Category 2 (Benign)	This is a normal assessment. Benign refers to a condition, tumor, or growth that is not cancerous. This means that it does not spread to other parts of the body. It does not invade nearby tissue. Essentially 0% likelihood of malignancy. [Breast Imaging Reporting and Data System—Mammography, Fifth Edition] Valid for the following modalities: MG US MRI NM.
  Category3	Category 3 (Probably Benign)	A finding assessed using this category should have a <= 2% likelihood of malignancy, but greater than the essentially 0% likelihood of malignancy of a characteristically benign finding. A probably benign finding is not expected to change over the suggested period of imaging surveillance, but the interpreting physician prefers to establish stability of the finding before recommending management limited to routine mammography screening. Six month follow-up and/or surveillance mammography is recommended. [Breast Imaging Reporting and Data System—Mammography, Fifth Edition] Valid for the following modalities: MG US MRI NM.
  Category4	Category 4 (Suspicious)	This category is reserved for findings that do not have the classic appearance of malignancy but are sufficiently suspicious to justify a recommendation for biopsy. There is a 2% likelihood of malignancy (cancer). Almost all recommendations for breast interventional procedures will come from assessments made using this category. [Breast Imaging Reporting and Data System—Mammography, Fifth Edition] Valid for the following modalities: MG US MRI NM.
  Category4A	Category 4A (Low suspicion)	Low suspicion for malignancy. A malignant finding is not suspected. A biopsy or other test will likely still be performed in order to determine. Tissue diagnosis may be recommended. Six month follow-up and/or surveillance mammography is recommended. Likelihood of malignancy is > 2% to <= 10% likelihood of malignancy. [Breast Imaging Reporting and Data System—Mammography, Fifth Edition] Valid for the following modalities: MG US MRI NM.
  Category4B	Category 4B (Moderate suspicion)	Category 4B: Moderate suspicion for malignancy. It warrants radiologic and pathologic correlation after tissue diagnosis. Likelihood of malignancy is > 10% to <= 50% likelihood of malignancy. [Breast Imaging Reporting and Data System—Mammography, Fifth Edition] Valid for the following modalities: MG US MRI NM.
  Category4C	Category 4C (High suspicion)	Category 4C: High suspicion for malignancy. Includes findings that have a high suspicion of malignancy but that are not highly suggestive of malignancy (category 5). Tissue Diagnosis is highly recommended. Range for likelihood of malignancy is > 50% to < 95% likelihood of malignancy. It is more likely malignant versus benign. [Breast Imaging Reporting and Data System—Mammography, Fifth Edition] Valid for the following modalities: MG US MRI NM.
  Category5	Category 5 (Highly Suggestive of Malignancy)	Highly Suggestive of Malignancy. Almost certainly predictive of breast cancer with a value of at least 95%. Tissue Diagnosis is highly recommended or required. [Breast Imaging Reporting and Data System—Mammography, Fifth Edition] Valid for the following modalities: MG US MRI NM.
  Category6	Category 6 (Known Biopsy-Proven Malignancy)	Known Biopsy-Proven Malignancy. Surgical excision when clinically appropriate. This category is only used for findings on a mammogram that have already been shown to be cancer by a previous biopsy. Mammograms may be used in this way to see how well the cancer is responding to treatment. [Breast Imaging Reporting and Data System—Mammography, Fifth Edition] Valid for the following modalities: MG US MRI NM.
