Nipple discharge is the most common complaint of patients seeking medical attention for breast disease, accounting for about 5% of all breast symptoms. Nipple discharge can be either pathologic or physiologic. Pathologic nipple discharge typically is unilateral, involves a single duct, is spontaneous, and may be serous or bloody/ bloodstained. Physiologic nipple discharge is usually bilateral, involves multiple ducts, and is white or green. Although ominous to patients, most pathologic nipple discharge is due to benign breast disease. Most of the women presenting with pathologic nipple discharge have been reported to have an underlying malignancy.
