BACKGROUND: Benign breast pathology is a common presenting complaint, and its assessment is important to characterise not to miss malignant pathology. At Helen Joseph Hospital (HJH), patients are triaged at the breast clinic according to the clinical suspicion of benign versus malignant disease. The patients are assigned a colour label based on their clinical presentation. This triage system affects waiting times between clinical examination and mammography appointments. This study aims to assess the association between clinical examination and the radiological and pathological findings of disorders deemed clinically benign, and to ascertain the spectrum of benign breast disorders encountered at HJHMETHOD: A retrospective study of imaging results of patients at HJH presenting as clinically benign breast disorders from January to June 2018 was conducted. Assessed Breast Imaging-Reporting and Data System (BI-RADS) score was noted and if core biopsies were performed, their results and patient demographics were documentedRESULTS: Of the 1 263 clinically benign patients presenting from January to June 2018, the radiological assessment was: BI-RADS 1: 158 (12.5%), BI-RADS 2: 685 (54.2%), BI-RADS 3: 292 (23.1%), BI-RADS 4a: 54 (4.3%), BI-RADS 4b: 29 (2.3 %), BI-RADS 4c: 21 (1.7%), BI-RADS 5: 24 (1.9%). There were 133 biopsies (including eight BI-RADS 3 patients), with 46 (3.6%) confirmed malignancies. The combined specificity of mammography and ultrasound was 65.52% (54.56-75.39%) and combined sensitivity 91.30% (79.21-97.58%CONCLUSION: There is a vast spectrum of benign conditions presenting in this population group with only 3.6% confirmed malignancies, confirming an accurate triage system utilised at the breast clinic. Radiological imaging is highly sensitive but less specific, emphasising the triad of clinical, radiological and histological assessment as the gold standard with regard to diagnosis of breast disease
