A woman with amenorrhoea due to hyperprolactinaemia does not develop the breast atrophy seen in postmenopausal women or in amenorrhoeic women who are gonadotrophin deficient or have primary ovarian failure.
On examination, the breast is well developed and the Montgomery tubercles are hyperplastic (Fig. 4.6). If the breast is correctly examined, first by expressing it from the periphery towards the areola to empty the milk ducts, followed by squeezing and lifting the areola (rather than the nipple itself) to empty the milk sinuses, galactorrhoea can usually be found.
