Breast BI-RADS5 is not necessarily advanced. Breast BI-RADS5 indicates a high probability of getting a tumor, at this time can not be completely sure whether the patient is a benign tumor disease or advanced malignant tumor disease, the patient needs to be clearly diagnosed through the node puncture biopsy, and then determine the patient’s stage of the disease. Tumor staging mainly depends on whether there are distant lymph node metastases, tumor size and whether there are distant organ metastases, while BI-RADS is the risk grading of the tumor only by ultrasound. If there is a BI-RADS category 5, it is necessary to puncture for further pathological examination to confirm whether it is a tumor or not, and to develop the next treatment plan. Therefore, BI-RADS category 5 is not necessarily an advanced stage of the tumor. Breast BI-RADS category 5 has a higher probability of malignancy, and if this condition is detected, it should be treated immediately in a large hospital or specialized hospital, which can effectively control the condition.
