Denise The green discharge you describe could be due to an intraductal papilloma or pre-existing fibrocystic breast disease and duct ectasia. There is a description of these conditions in all surgical textbooks, and a recent article in Modern Medicine August 1995 by Dr Paul Crea. (Benign breast disease, a management guide for GPs). This article states that 82% of discharges are benign. Ruth Lawrence's book (mine is 1989 edition) also covers this in some detail. Hope this helps Fiona Coombes a fellow LC in Australia
