Thank you for the question and picture. I would suggest that you seek consultation with board-certified plastic surgeons. Physical examination will be key when it comes providing you with an accurate diagnosis. Based on your description, it is possible that you are dealing with gynecomastia. "Gynecomastia" comes from the Greek meaning "gyne" meaning woman and "mastos" meaning breasts. It refers to abnormal development of large mammary glands in males. Although there may be many “causes”, most cases are idiopathic (no specific cause). The use of certain medications, drugs, organ dysfunction (kidney or liver), hormonal imbalances etc. may also be causative. Persistence gynecomastia is often best treated with partial excision of the prominent glandular tissue as well as liposuction surgery of the peripheral chest area. If the prominence of the chest wall is caused by adipose tissue liposuction surgery may suffice. If/when the time comes for surgical intervention, please make sure that you seek consultation with board certified plastic surgeons who can demonstrate significant experience achieving the types of outcomes you would be pleased with.You may find the attached link, dedicated to gynecomastia concerns, helpful to you as you learn more. Best wishes.
