Men with pain in the upper part of the breast: 1, to palpate whether there is a local lump, because in recent years it was found that the incidence of male breast development is significantly higher than before, and unilateral male breast development is more pronounced than bilateral. The patient should perform an ultrasound examination to see if there is a mammary gland hyperplasia and the size of the hyperplasia when palpating the local lump. If the patient’s appearance is affected, surgical treatment can be considered. 2. Patients should pay attention to whether there is a recent history of trauma, as trauma can also lead to local pain, which will gradually heal on its own, so there is no need to worry too much. 3. Men can also develop local infections, and local skin signs of congestion and edema can be found, and palpation is more obvious. The pain is more obvious and anti-infection treatment is needed.
