Role of digital breast tomosynthesis in the evaluation of focal breast pain.
RATIONAL AND OBJECTIVE: To investigate the utility of digital breast tomosynthesis (DBT) in the evaluation of focal breast pain, considering breast density and breast cancer risk. METHODS: Ninety-one cases of focal breast pain evaluated with DBT and ultrasound (US) from 12/30/2014 to 11/9/2017 with 2-year follow-up were identified. Exclusion criteria were non-focal, axillary, or radiating pain; palpable or skin changes; pregnancy or lactation; and history of ipsilateral cancer, trauma, or infection. Demographic data, Tyrer-Cuzick Score (TCS), medical history, breast density, imaging results, and pathology were recorded. Descriptive statistics were reported. RESULTS: Eighteen percent (16/91) of cases demonstrated findings, all benign. Of these, 6% (1/16) were detected by DBT only, 88% (14/16) by US only, and 6% (1/16) by DBT and US. US resulted in 3 benign biopsies. Ninety-nine percent (75/76) of cases with no findings at the site of pain on US also had no findings on DBT. Ninety-eight percent (89/91) of cases with no cancer detected at the site of pain on US also did not have cancer on DBT. DBT detected 2 incidental cancers not associated with pain. DBT and US agreed that there was no finding at the site of pain in 82% (75/91) of cases. A high degree of agreement between DBT and US was seen when stratified by breast density and TCS. CONCLUSION: DBT may be appropriate for the evaluation of focal pain. Low breast cancer incidence was observed at the site of focal pain across all mammographic breast densities and breast cancer risks.
