Lactation is common after a woman has given birth, and it can sometimes occur during pregnancy too. However, it is possible for both women and men to produce a milky discharge from one or both nipples without being pregnant or breastfeeding. This form of lactation is called galactorrhea. Galactorrhea is unrelated to the milk that a woman produces when breastfeeding.
People may worry about unexpected nipple discharge, but there is no link between galactorrhea and breast cancer. In this article, learn about the possible causes of lactating without being pregnant or breastfeeding, as well as when to see a doctor. The hormone prolactin causes lactation during pregnancy and while breastfeeding. People who have galactorrhea may produce too much prolactin. The pituitary gland, which is a small gland at the base of the brain, makes and regulates prolactin and several other hormones.
Problems with the pituitary gland, such as a noncancerous tumor or another pituitary disorder, can sometimes cause people who are not pregnant to lactate. In rare cases, people may lactate due to an emotional response to an unrelated baby. One study described a young woman with type 1 diabetes whose nipples produced milky discharge under gentle pressure when she was near an unrelated newborn.
Her symptoms went away when she was no longer near the baby. Doctors ruled out all possible biological causes for lactation.
