The risk of low-grade intraductal carcinoma is very low, because the malignancy of low-grade is originally low, plus the tumor is only confined to the duct and does not break through the duct and grow in all directions, so it should be the earliest tumor and will be fine after surgical removal. Therefore, it should be the earliest tumor, and it will be fine after surgery. After surgery, there is no need for radiotherapy and chemotherapy, and it can be cured by surgery alone. However, regular review is needed after surgery because the possibility of malignant tumor in the organ cannot be ruled out, and regular review can detect the problem and deal with it in time. Although the risk of low-grade intraductal cancer is very low, there is no guarantee that problems will not occur in the future.
