Nipple Discharge: When is it Worrisome?

Nipple discharge is the third most common breast related complaint seen in the breast clinics. Although the majority of cases are due to a benign etiology, 5%-12% cases of pathological nipple discharge may be harboring an underlying malignancy. A thorough radiological workup in cases of pathological nipple discharge is thus of utmost importance, with the initial imaging modality depending on the age of the patient. The imaging modalities include mammogram (MG) and ultrasound (US) with addition of breast MRI if the nipple discharge is clinically suspicious and no MG or US correlate is identified. Magnetic Resonance Imaging (MRI) also holds promise in demonstrating the exact extent of a pathology detected on US and thus aids in the planning of further management.
