Nipple Discharge
Pathophysiology of Nipple Discharge
Nipple discharge may be breast milk or an exudate produced by a number of conditions. Breast milk production in nonpregnant and nonlactating women ( Prolactinoma ) typically involves an elevated level of prolactin, which stimulates glandular tissue of the breast. However, only some patients with elevated prolactin levels develop galactorrhea.
