Numbers are frequencies unless otherwise indicated.
Screening Mammography Examinations: mammography examinations indicated by the radiologist to be for screening, with bilateral routine views done and no other mammogram within the last 9 months, among women without breast implants.
* Sensitivity = the percentage of cancers that had an abnormal initial interpretation (BI-RADS category 0, 4, 5; Note: 3 with a recommendation for immediate follow-up was recoded as 0).
† True Positive = the number of cancers that had an abnormal initial interpretation.
‡ Cancers = the number of examinations with a tissue diagnosis of cancer within 1 year following the examination.
§ Specificity = the percentage of non-cancers that had a negative initial interpretation (BI-RADS category 1, 2, or 3 with no recommendation for immediate follow-up).
|| True Negative = the number of non-cancers that had a negative initial interpretation.
# Non-cancers = the number of examinations without a tissue diagnosis of cancer within 1 year following the examination.
