Yes, you should make an appointment with your health care provider (HCP). A discharge from your breast could mean that your breast is infected, that a breast duct is dilated (widened), or that you have a hormone imbalance. When a milky discharge comes from a young woman’s breast when she is not breast feeding, it’s called “galactorrhea”. This condition can result from taking certain medicines such as birth control pills or anti-depressants, from being pregnant or recently being pregnant, from low thyroid hormone levels, or rarely from a small benign (not cancerous) pituitary tumor. Your body may be making extra amounts of the hormone “prolactin”, which can cause a white discharge from your nipples. Anytime you have any sort of breast discharge, fluid or blood that comes from your breast, you should make an appointment with your HCP.
