The higher the value, the greater the risk. 3 types of nodules are mostly considered benign breast nodules, but cancer is not ruled out, the chance is about 2%, which is a more ambiguous type, and requires about six months of follow-up and review. If the nodule does not increase in size and there is no abnormal change in the nodule shape, it can be considered as benign nodule and does not require treatment. On the contrary, if the nodule grows too fast or is accompanied by other abnormalities, it needs to be removed surgically and sent for pathological examination to clarify the nature of the nodule. If the breast bi-rads are examined in category 3, they need to be closely observed for any abnormal changes.
