Men have breast tissue too, just less of it. Male breast cancer most often presents as a small hard lump near the nipple, and it is frequently found later simply because fewer men know it can happen.
Signs in men
- A lump, usually under or around the nipple
- Discharge, bleeding or crusting of the nipple
- Skin changes or a sore that does not heal
- Swelling under the arm
Because male breast tissue is thin, lumps are often felt quickly — which can favour early detection once they are checked. Male breast cancer is treated exactly like breast cancer in women.
