Definition of Intraductal Papilloma of Breast
A benign (noncancerous) tumor that grows within a lactiferous duct (milk duct) of a woman’s breast. Intraductal papilloma is the most common cause of nipple discharge, which is its primary symptom. The discharge may be milky, clear, or blood tinged. A woman may notice only slight staining on her clothing.
There is usually no pain or discomfort associated with intraductal papilloma.
The tumor causing symptoms may be too small for the woman or her health-care provider to feel, though may appear on mammogram and usually shows up on ultrasound of the breast. Other diagnostic procedures may include a contrast X-RAY called a ductogram and laboratory analysis of the nipple discharge.
Biopsy of the papilloma, usually in combination with its surgical removal, provides definitive diagnosis. Intraductal papilloma occasionally recurs.
