Because men’s breasts are small, it is easy to detect when a small swelling appears in the male breast. Compared to women, it is easier to detect the problem earlier when there is a lesion in the male breast as long as you pay more attention to it in general. When the following conditions appear in the male breast, you should go to the hospital for further examination as soon as possible 1. Lumpy and swollen feeling. The main symptom of male breast cancer is that lumps in the breast often occur around the areola, with hard texture and unclear borders, and the surface is often not smooth and less mobile. 2. Sunken breast skin. Inverted nipple, occasionally accompanied by nipple blood spill. The pain is sometimes not very obvious, but if nipple retraction is found and the skin is involved, one should be alert. 3. Enlarged lymph nodes. The most important feature of breast cancer tumor is that it is easy to metastasize, so if you find swollen lymph nodes in the armpit for a long time, you should also be especially careful.
