Nipple discharge in non-lactating breast is classified as 2 groups. The first group is stagnation dischargewhich is determined by an apocrino-like exfoliation and stagnation within the ductal system. The second group ishyperplasitc or neoplasitc group. The secretory breast disease combined with nipple discharge can not be diagnosedby simple X-ray mammography of ultrasonography. For differential diagnosis of secretory breast disease and forlocalization of lesions, the galactography is necessory. We analysed 49 cases of galactography in non-lactatingbreat and obtained following results. 1. The most common cause of dischage was duct ectasis (39%) in stagnationdischarge group and papilloma (23%) in hyperpiastic discharge group. 2. Hyperplastic discharge group occured mostfrequently in 5th decade of age and was discovered more frequently in fatty parenchymal pattern on simplemammography. 3. The most frequent type of nipple discharge was cloudy-milky type in stagnation group and bloodynature in hyperplastic group. 4. The most common cause of bloody discharge was papilloma(58%). 5. The bloodynipple discharge among 56 cases of breast cancer during 4 years occured only in 5 cases (9%).
