The evaluation of breast cancer in males begins with a medical history and physical examination.

Physical findings of breast cancer in males may include:

• New breast lump
• Changes in breast shape or size
• Dimpling in the skin of the breast
• New lump in the armpit that does not go away
• Nipple discharge from one breast
• Orange-peel color of the skin overlying the breast
• Retracted (pointing inward) nipple or changes in the nipple

Testing is required to evaluate breast cancer in males.

Tests that may be used to evaluate breast cancer in males include:

• Breast biopsy
• Nuclear scanning of the breast (Miraluma)
• Nuclear scanning of the bones (to look for cancer that has spread)
• Breast ultrasound:
• May help to identify breast swelling caused by a cyst.
• Sentinel node biopsy
• Hormone receptor status
• Mammography:
• This is a special x-ray that can reveal close to 90% of all breast cancers.
• Enhanced MRI of breast
