Overview Symptoms Treatment Prevention

Intraductal papilloma

• breast pain
• nipple discharge, sometimes bloody, from one breast only
• staining may be noticed inside the bra and/or clothing
• breast lump
• breast enlargement

• Intraductal papilloma is the most common cause of spontaneous nipple discharge from a single duct.
• A small lump beneath the nipple may be felt by the examiner, but it is not always palpable (able to be felt with the fingers).
• A mammogram often does not show papillomas. Ultrasound may be helpful.
• An x-ray with contrast injected into the affected duct (ductogram) may be performed.
• Cellular (cytologic) examination of discharge may be performed to identify potentially malignant (cancerous) cells.
• A breast biopsy is necessary to make a definitive diagnosis and rule out cancer.
