The normal male breast contains both fat tissue and glandular tissue.   The breast tissue is usually small in volume and localized immediately under the nipple, is firmer then the surrounding fatty tissue and feels like a small lump. Pseudo-gynecomastia is an enlarged male breast caused by excessive fat tissue, but which contains a normal amount of glandular breast tissue. The condition is very common as men become older and in younger men who are relatively obese. Some medications and drugs-including marijuana are a contributor factor to gynecomasty. Men with excessive fat in their breasts are excellent candidates for liposuction.
