Intraductal papilloma
Pronunciation
Definition 1
A benign (not cancer), wart-like growth in a milk duct of the breast. It is usually found close to the nipple and may cause a discharge from the nipple. It may also cause pain and a lump in the breast that can be felt. It usually affects women aged 35-55 years. Having a single papilloma does not increase the risk of breast cancer. When there are multiple intraductal papillomas, they are usually found farther from the nipple. There may not be a nipple discharge and the papillomas may not be felt. Having multiple intraductal papillomas may increase the risk of breast cancer. Also called intraductal breast papilloma. (NCI Dictionary)
Definition 2
An intraluminal papillary epithelial neoplasm arising within the ducts. Representative examples are the intraductal breast papilloma and the salivary gland intraductal papilloma. (NCI Thesaurus)
Definition 3
A small, often impalpable benign papilloma arising in a lactiferous duct and frequently causing bleeding from the nipple. (Stedman, 25th ed) (NLM, Medical Subject Headings)
