Ductal tumors of the breast are also known as intraductal papillomas. Surgery for intraductal papilloma should be selected according to the patient’s lesion grading and staging, age, physical condition and other factors. 1. For solitary intraductal papilloma, with clear localization, excision of the duct and surrounding breast tissue at the lesion site can be done. 2. If there is malignancy, radical mastectomy should be performed according to the surgical method for breast cancer. 3. For older patients with active ductal epithelial hyperplasia or mesenchymal degeneration, simple mastectomy can be performed after seeking consent from the patient and family. 4. If the stage is too high to be operated, or the physical condition is too poor to tolerate surgery, chemotherapy can be performed to shrink the tumor and downgrade the stage. Meanwhile, in recent years, with the development of minimally invasive technology as well as preoperative biopsy and assisted localization, minimally invasive surgery has been developed rapidly in this field, which makes the scope of surgical resection largely narrowed down, but the details should also depend on the situation. Intraductal papilloma is generally considered benign, but the malignancy rate is 6%~8%. After the onset of the disease, you should go to the hospital and choose the appropriate surgery under the guidance of your doctor to avoid delays.
