Intraductal papillomas vary in size, are usually located around the areola, and generally do not exceed 1 cm in diameter. This is an intraductal papillary epithelial trait that occurs mainly within the ducts under the areola and consists of fibrovascular coated epithelial cells that are soft in texture. The etiology of the condition is not clear, but may be related to estrogen and other reproductive hormone stimuli, which cause ductal dilatation and proliferation of mammary epithelial cells, promoting the development of intraductal papillomas. Most of the intraductal papillomas are small in size and often cannot be palpated. A few of them can be palpated as breast lumps, which are mainly located around the areola and usually do not exceed 1 cm in diameter, and there may be fluid spillage from the nipple of the lump when it is pressed. It is recommended that the patient can go to the breast surgery department of the hospital for consultation, and can cooperate with the doctor to take open surgery or mastectomy surgery treatment, specific to follow the doctor’s instructions.
