Differential diagnosis of nipple discharge

: An analysis of results of contrast mammography in 42 women having spontaneous, persistent and unilateral discharge from the nipple of the breast of serous, serous-hemorrhagic and hemorrhagic character was made. The cause of the discharge was found to be intraductal papillomas and cystadenopapillomas in 55% of the cases, breast cancer--in 2% which were not diagnosed by noncontrast mammography.
