Diagnostic Approach for Nipple Abnormalities in Elderly Males
Critical Risk Stratification
- Male patients with nipple discharge or nipple abnormalities have a 23-57% incidence of breast cancer, according to the American College of Radiology 1, 3
- Patients over age 60 with pathologic nipple findings have a 32% cancer risk, as reported by the American College of Radiology 1, 2
Immediate Imaging Algorithm
- Mammography should be the initial imaging study for male patients with nipple abnormalities, as recommended by the American College of Radiology 3
- The sensitivity of mammography ranges 15-68% for detecting malignancy, but remains essential for identifying suspicious microcalcifications associated with DCIS, according to the American College of Radiology 1, 2
- Ultrasound is as useful in male patients as in female patients for identifying and localizing lesions, and should be performed in conjunction with mammography, as stated by the American College of Radiology 1, 3
Tissue Diagnosis Pathway
- Image-guided core needle biopsy is preferred over fine needle aspiration for definitive pathologic assessment, as recommended by the National Comprehensive Cancer Network 2
- Ultrasound guidance can localize and direct biopsy of image-detected lesions, according to the American College of Radiology 1
- Consider breast MRI with and without IV contrast, which has 86-100% sensitivity for detecting causes of nipple abnormalities, as suggested by the National Comprehensive Cancer Network 2
