Mammograms are becoming more and more important to women, but when you get the results: Breast BI-RADS* grade, maybe you are confused! First of all, let’s take a look at the full name of breast BI-RADS grading: Breast imaging reporting and data system, translated as (Breast Imaging Reporting and Data System), which was first created and recommended by the American College of Radiology (ACR) as a standard for indicating breast changes. What is the significance of BI-RADS grading? Grade 0: The imaging assessment is incomplete and further evaluation is needed, which is recommended in combination with other clinical examinations, or other imaging examinations. Don’t think that grade 0 means nothing! Grade I: Negative, no abnormalities seen. Grade II: benign changes are considered and regular follow-up (e.g., once a year) is recommended. Grade III: benign disease is possible, but the follow-up period needs to be shortened (e.g., once every 3-6 months), and the percentage of malignancy at this level is less than 2%. Grade IV has been divided into three levels of ABC Grade IVA low malignancy, puncture biopsy is recommended, the results are benign follow-up is recommended. Grade IVB poisoning suspicious malignancy, suggest puncture biopsy, if papilloma suggest excisional examination. IVC grade moderate concern (atypical malignant signs) suggest biopsy, pathologists should be cautious in taking such tissues, and if benign should be followed up for a short time. Grade V: Highly suspicious of malignant lesions (>95% identified as malignant disease), requiring surgical excisional biopsy. Grade VI: Malignant lesion has been confirmed by pathology. Surgical excision. After understanding the meaning of BI-RADS grading, when you get the hospital imaging report (mammogram, ultrasound and MRI report), you do not need to be nervous when you see the diagnosis first, do not think that the report BI-RADS so-called grade I and II is the stage I and II of breast cancer. In fact, only grade III onwards needs to be treated with caution. Of course, the degree of breast disease judged from the imaging needs to be analyzed by clinicians in a comprehensive manner before giving treatment recommendations.
