Men can also have problems with enlarged breasts, so-called gynecomastia. Some men’s mammary glands go through a period of excessive development in puberty, making the chest look feminine, but this can also be caused by hormone treatment, for instance in connection with prostate cancer. Some men also have a tendency to store fat in this area, so called pseudo gynecomastia.

Before an operation the breast tissue is examined. It is then possible to assess the extent to which the enlarged chest area is caused by excessive mammary gland development and how much is fatty tissue. These two components are removed surgically in different ways. Inexplicable mammary gland growth in men sometimes requires further medical investigation into the hormonal balance. Otherwise no special investigations are needed.
