Man with a breast lump/tenderness

Male patients are managed similarly to women when they have breast symptoms. Tender retroareolar breast lumps are most commonly due to gynecomastia (uni or bilateral), but men do develop breast cancer (0.05% of all breast cancers), vast majority are infiltrating ductal cancers.

  • Mammography is performed bilaterally (for comparison)
  • Ultrasound may or may not be performed – not usually needed if classic mammographic features of gynecomastia are present.
  • Breast cancers are similar in appearance to female tumors
  • Gynecomastia appears as a flame shaped subareolar opacity, often bilateral but asymmetrical.
