WHAT IS A GYNECOMASTIA?
Gynecomastia is a condition that causes the enlargement of the breast tissue in boys or men. It is usually caused by an imbalance of the hormones estrogen and testosterone, which can occur naturally or due to certain medications or health problems. Gynecomastia can affect one or both breasts, sometimes unevenly, and can cause pain, tenderness, or embarrassment. Gynecomastia is not a serious health problem, but it may affect your self-esteem and emotional well-being.
