Enlargement of the breasts in men, known as gynecomastia, can be a significant cause  of embarrassment and self-consciousness.  Although this can be related to certain medications or underlying medical problems, most often there is no identifiable physiologic cause. The enlargement may be related to fatty tissue or firm glandular tissue

This can be treated, reducing the volume of excessive tissue, with a combination of excision and liposuction.  In some cases, liposuction alone can provide adequate treatment.
