Gynecomastia sucks! There is no other way to say it. Gyno is usually caused by an excess of breast tissue, excess fat or more commonly a combination of both. Looking at your picture it appears there is definitely excessive fullness of the right chest (less noticeable on the left because your arm is raised). This type of gyno would be mild to moderate and is correctible with liposuction (minimal scarring).
From your photo, it seems evident that you have gynecomastia. Typically, treating gynecomastia involves a combination of directly removing excess breast tissue under the areola and contouring the chest with liposuction. While some patients may only require contouring with liposuction, most will benefit from some level of direct excision of the breast.Best regards,Dr. B.
