How should imaging be approached in male breast disease?

• A. Begin with clinical assessment and ultrasound as the primary modality; mammography may be used; gynecomastia is common, but focal masses require evaluation for possible malignancy; management follows female breast cancer principles when indicated.
• B. Mammography only.
• C. MRI first.
• D. No imaging needed.

Answer: (A)

Imaging in male breast disease starts with clinical assessment and ultrasound as the primary modality because the male breast is small and dense, making ultrasound the most practical first look to characterize a palpable lump. Ultrasound helps distinguish benign patterns, like gynecomastia, from focal masses that could warrant further workup. Gynecomastia is common and has recognizable ultrasound features; when a discrete lesion or persistent focal mass is present, it prompts evaluation for possible malignancy. Mammography is added when indicated—such as in older men or when ultrasound findings raise suspicion—to better characterize any suspicious features and to guide biopsy if needed. MRI is not used first; it’s reserved for problem-solving in select situations or to assess extent once cancer is suspected or confirmed. If imaging or exam raises concern for cancer, proceed with the standard cancer workup and treatment principles used in female breast cancer, adapted to male anatomy and tumor biology. No imaging is appropriate when a lump is present.
