Nipple Discharge
Key Points
Usually, the cause of nipple discharge is not cancer. If the discharge comes from both breasts or from several milk ducts and is not bloody or pink, the cause is usually a noncancerous hormonal disorder. If the discharge comes from only one breast and is bloody or pink, cancer is possible, especially in women aged 40 or older. Whether blood tests, imaging (such as ultrasonography), or both, are done depends on the suspected cause.
