Normal males have one pair of breasts, but individual males develop multiple nipples or breasts in places such as the armpits or groin, known as male secondary breasts. Male secondary breasts may appear as localized skin bulges around the armpits or near the chest, and in some cases, subcutaneous cysts may be present. There may also be soreness and swelling if the swelling appears near the chest. Different treatments are needed for different symptoms. If the male secondary breast is small and there are no obvious symptoms, no special treatment is needed. If breast enlargement occurs in male secondary breasts, the probability of cancer will be higher, and timely surgical treatment is recommended, so the treatment of male secondary breasts needs to be emphasized. If the male paratesticular breast is large, it is recommended to go to the hospital in time, and under the guidance of the doctor for surgical excision treatment.
