- A benign (noncancerous), wart-like growth in a milk duct of the breast. It is usually found close to the nipple and may cause a clear, sticky, or bloody discharge from the nipple. It may also cause pain and a lump in the breast that can be felt or seen. It usually affects women aged 35-55 years. Having an intraductal papilloma does not increase the risk of developing breast cancer.
