Gynecomastia is an enlargement of the male breast resulting from a proliferation of the glandular component of the breast.

The causes are numerous, including hormonal changes, marijuana or steroids use and excess of weight. But in many cases, there is no clear cause.

Clinically, gynecomastia is mostly seen at puberty and after the age of 50, both physiological hormonal variation periods. At puberty, gynecomastia is generally bilateral and not localized and diminishes spontaneously within a year or 2.

The treatment is adapted to each patient. If there is an excess of glandular tissue, an incision will be done under the gland in order to excise it. A liposuction can also be done at the same time.

If the cause is mainly an excess of fat, a liposuction can be sufficient. On the other hand, when an excess of tissue is present, its excision is necessary.
