The most common cause of galactorrhea is nonpuerperal hyperprolactinemia, or excessive amounts of prolactin in the blood not related to pregnancy or childbirth. These processes are chiefly hormone imbalances caused by hypothalamic-pituitary disturbances, pituitary tumors, or neurologic damage. Galactorrhea is not due to infection, tissue injury, or cancer.
