Abstract
Background: Mammography and breast ultrasound are screening methods for diagnosing breast lesions. Reports of BI-RADS 4 and 5 should be verified with pathology because there is a high chance of cancer.
Objectives: This research aims to predict the positive predictive value (PPV) of mammography and breast ultrasound in BI-RADS categories 4 and 5 and to study the relationships with pathological results.
Methods: This retrospective descriptive study was conducted with 442 cases included. Descriptive statistics analyzed general data, clinical data records, and PPV—the relationship between pathological results using the Chi-Square.
Results: 53.1% of the samples who were found with a lump in the breast were diagnosed with breast cancer. 22.4 % of the samples were found with a lump in the breast, a fibroadenoma. 19.7% of the samples had the PPVs of mammography and breast ultrasound in BI-RADS categories 4A, 4B, 4C, and 5. A lump size of 2 cm. or more had a higher risk of developing breast cancer than those with a lump size less than 2 cm at 2.68 times. The BI-RADS 5 group had a higher risk of developing breast cancer than BI-RADS 4 at 16.95 times.
Conclusions: The size of the lumps found and the PPVs of the BI-RADS 4 and 5 can effectively predict the likelihood of developing breast cancer.
