Last week on ABC's Grey's Anatomy the episode highlighted a plastic surgery procedure that isn't talked about as heavily as say breast augmentation, rhinoplasty, etc.
A lot of people don't understand the condition Gynecomastia so here is a little more information about the topic:
One of the most common misconception is that Gynecomastia can easily be "solved" by weight loss, which is not factual.
Gynecomastia is a result of the development of abnormally large mammary glands in men resulting in what appears to be male breasts. Specifically it is characterized by excess glandular tissue development and localized fat or a combination of both.
