Introduction. Breast Cancer is a disease of public health, its prevalence is greater than the uterine carcinoma and mortality poses a risk to be faced. One important coping strategies is prevention, this is where the BIRADS system plays an important role. Objective. Identify, review and assess the categorization of BI - RADS system and biopsied breast lesions in patients of H.M.I. 2013 - 2014. Material and Methods. Diagnosis test. Imaging results were obtained, either ultrasound, or ecomamograficos mammographic system by BlRADS result of histopathological lesions studied by biopsy. OpenEpi program and evaluation of diagnostic test or screening for each category was applied. Results. The study found: BI-RADS 3, the sensitivity was 24.3% and 100% specificity with a PPV of 100% and NPV of 6.66%. BIRADS 4th sensitivity was 61.54% and specificity 94.87%, with a PPV 80% and NPV 88.1%. The BI-RADS 4B showed a sensitivity of 50% and a specificity of 94.87% with a PPV of 60% and a NPV of 92.5%. The BI-RADS 4c has a sensitivity of 83.33% and specificity 94.87%, the PPV is 71.43% and 97.37% VPN. The BIRADS 5 showed a sensitivity 87.5% and specificity 94.87% with a corresponding PPV of 77.78% and NPV of 97.37%. Conclusion. Imaging reports reported by BI-RADS system have proven reliable in the detection of patients with malignancies and as a source to determine the healthy patients or with benign findings. Finally it should have special attention to patients with imaging reports BI-RADS 3 in order to rule out malignancy.
