Breast lesions were diagnosed in 1518 patients among 8432 who had had mammography [ 19%]. In 324 there was the characteristic appearance of "secretory disease" . Additional uni- or bilateral galactography was performed in 458 womenbecause of breast secretion. A normal milkduct system was found in 29.6% of them; ductalectasia with a lumen above 3 mm diameter was present in 14.6%. The most common cause ofsecretions was small cysts as part of a small-cystic mammary fibrosis or fibrocysticdisease of the breast [ 32.6%]. Intraductal proliferation was present in 21% of allgalactograms, occult carcinoma in 3 [ 0.7%]. It would seem that a secreting breast isnot as common an early symptom of mammary carcinoma as sometimes stated. The most commoncomplication of galactography was mastitis [ more or less severe], almost always re-sponding to oxyphenbutazone administration.
