There is usually no such thing as the top five early symptoms of male breast cancer. Male breast cancer is relatively rare, and the incidence rate accounts for about 1% of breast cancer. The clinical manifestations are similar to those of female breast cancer, mainly due to the pressure and pulling of the cancerous tissues on the breast, and the possible early symptoms include breast lumps, breast pain, nipple retraction, skin changes and nipple overflow: 1. Men should be alert to the appearance of breast lumps and go to the hospital in time to clarify the nature of the lump. 2. Skin changes: Orange peel-like changes in breast skin are usually special signs of early male breast cancer, as the lymphatic ducts in the breast are blocked by cancer cells, causing lymphatic flow obstruction, resulting in orange peel-like changes in breast skin. 3. Nipple retraction: male breast is smaller and can be pulled by cancerous tissues to make the nipple retract. Breast pain: breast pain is less obvious in early stage of male breast cancer, but if the lump presses on nerves or tissues, it can cause vague pain or stabbing pain in the breast; 5. Nipple overflow: some male breast cancers can show nipple overflow in early stage, which is relatively rare. Both male and female breast cancers generally do not show obvious discomfort in the early stage, and occasionally the above symptoms may appear. As the disease progresses, the symptoms may become more frequent and more pronounced. Those who have symptoms or have a family history of breast cancer should seek medical examination as soon as possible.
