Less than 1% of all breast cancers occur in men, and although the disease is rare, the incidence appears to be increasing. Because men usually do not suspect breast cancer when they feel a lump in the breast, diagnosis frequently is delayed. Although screening for breast cancer is not recommended for men, radiographic imaging plays an important role in distinguishing benign conditions from malignant disease, and mammography usually is recommended as the first radiographic assessment. Ultrasonography is useful in differentiating between noncancerous cysts and solid malignant tumors, especially if coexisting gynecomastia masks a cancerous lesion on mammography. Sonography also is useful to guide breast biopsy.
所有乳腺癌中男性患者不到1%，尽管这种疾病很罕见，但发病率似乎在上升。由于男性乳房出现肿块时通常不会怀疑是患了乳腺癌，所以诊断常常会延迟。虽然不建议对男性进行乳腺癌筛查，但影像学检查在区分良性病变和恶性疾病方面起着重要作用，通常建议将乳房X线摄影作为首选的影像学评估方法。超声检查有助于鉴别非癌性囊肿和实性恶性肿瘤，特别是当同时存在男性乳腺增生掩盖了乳房X线摄影检查中的癌性病变时。超声检查也有助于指导乳房活检。
