Breast ductal tumor is a disease that is not necessarily treated by minimally invasive surgery, but may also be treated by other surgical methods, which need to be decided by the patient’s own condition. Breast ductal tumor generally refers to the papilloma that occurs in the epithelium of the breast ducts. Patients usually have symptoms such as bloody overflow, breast lumps, etc. Some patients’ symptoms are not very obvious, and they are only found during physical examination. The treatment of patients is mainly surgical excision treatment, and the common minimally invasive surgery nowadays includes minimally invasive surgery under fiberoptic ductoscopy and minimally invasive rotary osteotomy of McMurray, etc. Minimally invasive surgery has a smaller surgical incision and a smaller postoperative scar, but is not applicable to the patients with deeper lesions and thin breast ducts, which makes it inconvenient to insert the mastoscope. Patients with more severe lesions and larger masses can undergo traditional surgical procedures such as lobectomy, quadrantectomy, and subcutaneous mastectomy. Therefore, patients with ductal tumors of the breast do not always undergo minimally invasive surgery, and patients should choose the appropriate surgical procedure based on their own situation and under the advice of their doctors.
