Hi
Welcome to the MedHelp forum!
Breast enlargement in adult men is usually due to imbalance of sex hormones and more of estrogen and less of testosterone. At times it is a false or pseudo breast enlargement and happens due to excess deposition of fat. In such cases surgery is the treatment to remove excess fat. Please consult an endocrine specialist or your PCP to get this evaluated.
Hope this helps. Please let me know if there is any thing else and do keep me posted. Take care!
Have you had your testosterone checked? Men go thru andropause just as women go thru menopause. Your testosterone drops and you need to get injections to rectify the problem, my husband has been on them for years. It can cause many problems including brittle bones.
