You can have treatment for gynecomastia at any age as long as you are healthy enough to tolerate the procedure/anesthesia. The key to treatment is the quality of your skin. As we age our skin becomes less elastic and doesn't spring on back like the youngsters. Therefore, your surgeon has to treat things a bit differently so that you don't end up with significant irregularities because of poor skin retraction. Often with patients of your age (mine as well), we are willing to accept imperfections better than when we were younger. Who wants female like breasts when you don't have to live with them? Better to have a scar or imperfection rather than breasts.
