NCIt definition : A benign papillary neoplasm that arises anywhere in the ductal system of the breast.
It is characterized by the presence of fibrovascular structures lined by benign epithelial
and myoepithelial proliferations. Intraductal breast papillomas are classified as
central, when they arise in large ducts, or peripheral, when they arise in the terminal
ductal lobular units.;
Alternative definition : NCI-GLOSS: 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 breast 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 breast papillomas may increase the risk of
breast cancer.;
