Intraductal papilloma of the breast. Definition

Medical Definition: Intraductal papilloma of the breast

A benign (noncancerous), wart-like, in a milk duct of the breast. It usually is located near the nipple and may cause nipple discharge. It can also cause pain and a lump in the breast that can be felt. It usually affects women 35 to 55 years old. Having a single papilloma does not increase the risk of cancer. When there are multiple intraductal papillomas of the breast, usually away from the nipple, there may be discharge and may not be palpable. Having intraductal papillomas of the breast can increase the risk of breast cancer. Also called intraductal papilloma.
