Gynecomastia is the excessive development of the mammary glands in men, resulting in abnormally large male breasts. There are various causes of gynecomastia. When it is related to weight gain, it is called adipomastia. It can also arise during adolescence or in the elderly, affecting one or both breasts.

It is rarely discussed, but between 40% and 60% of men have mammary hypertrophy. Concept Clinic is establishing safe surgical solutions for the treatment of gynecomastia.
