“What is a breast papilloma, and is it cancer?
Also called intraductal papilloma, a breast papilloma is a small, wartlike growth in the breast’s milk ducts. This benign (noncancerous) condition may cause a clear or bloody discharge from the nipple, or you may feel a small lump behind or next to the nipple. Having one papilloma does not raise your breast cancer risk, though having several of these growths has been linked to higher risk.”
