Intraductal papilloma is usually a benign tumor, but it can also become malignant and needs to be treated by completing relevant tests. Intraductal papilloma is usually a proliferation of dilated ductal epithelium, blood vessels, and connective tissue, followed by papillary lesions, most of which are benign. Patients usually have no conscious signs and the tumors are relatively small and difficult to palpate. However, it has a certain chance of malignant transformation, which is about 6%-8%. Therefore, it is recommended that patients should visit a regular hospital for general surgery or breast surgery to improve the relevant examination and treatment under the guidance of doctors. Currently, surgery is the main treatment method, and preoperative endoscopy or mammography is required to facilitate the operation. In addition, patients need to take better care of their breast tissue after surgery and come to the hospital for regular checkups to understand the recovery of breast tissue.
