Abstract: Of all the malignancies to exist, breast cancer is and continues to be one of the most pervasive cancers. For the first time, female breast cancer was the most commonly diagnosed cancer surpassing lung cancer as reported by the American Cancer Society (ACS) and the International Agency for Research on Cancer (IARC) of 2020. Breast cancer is considered to be a heterogeneous disease due to its presentation of a wide variety of morphological, histopathological and biological features. Aim of the Study: To analyse the concordance of ultrasound findings of BI-RADS categories 2, 3, 4 and 5 lesions with histopathological biopsy results and calculate the predictive value and diagnostic accuracy of BIRADS. Materials and methods: It isa retrospective study, data were collected over a period of 5 years, from 2016 to 2020. Data from a total of 190 patients with related symptomatology and breast lumps who underwent ultrasound examination by expert radiologists were collected. The data were also correlated with pathological findings for those patients who underwent biopsy, the two were correlated. Results: BIRADS Lexicon had a high sensitivity of 95.23%, and the specificity and diagnostic accuracy were calculated to be 92.78% and 94.89% each respectively. BIRADS 2&3 had a high NPV of 97.82% and 4 and 5 had a PPV of 85.10%. The fact that there is a relatively high NPV for the lower BIRADS categories can be exploited and biopsies can be largely avoided in these cases. The high sensitivity of the BIRADS lexicon makes ultrasound a close alternative for mammography in the preliminary screening of breast lesions
