NCIt related terms : Ductal papilloma; Duct adenoma, NOS;
NCIt definition : An intraluminal papillary epithelial neoplasm arising within the ducts. Representative
examples are the intraductal breast papilloma and the salivary gland intraductal papilloma.;
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 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.;
