Gynecomastia is the benign growth of excess breast tissue in males, causes abnormally large breasts. Gynecomastia can occur in one or both breasts and starts as a small lump beneath the nipple, which may be tender. Often, the breasts enlarge unevenly. Gynecomastia that occurs during puberty is not uncommon and 75% of cases resolve themselves over a period of months without treatment.
There are two types of sex hormones: androgens and estrogens. Androgens (male hormones) are responsible for hair growth, regulating muscle size, and a developing a deep voice. Estrogens are hormones responsible for female characteristics. All men have both androgens and estrogens.
Generally, gynecomastia occurs from an imbalance in these hormones, where estrogen levels are higher than androgens like testosterone. It is important to note that over half of boys develop gynecomastia during puberty.
Gynecomastia can sometimes occur as an unusual condition associated with disease or metabolic disorders, or as a side-effect of certain medications, due to the natural decrease of testosterone production in older males.
Other causes of gynecomastia include:
A breast reduction, targeted liposuction, or a combination of the two can be performed in order to remove or reduce the excess breast tissue. Dr. Fiorillo will assess your particular case and determine what forms of treatment are best for you.
