Gynaecomastia is the growth of mammary gland in men. This may be caused by hormonal changes of the patient, for disorders during development at puberty, for medical treatments where they use hormones that produce breast growth, such as hormone therapy for prostate cancer.

Before the procedure is important a proper medical evaluation to determine what percentage is glandular and what is fat.

The surgical treatment consists in the treatment by liposuction and/or removal of the mammary gland. It is done through an incision in the lower halfround of the teat, scar that after procedure is almost imperceptible. Skin may also require resection, if the patient is an obese patient and lose a lot of weight or if breast growths major producing a large excess skin that may be collected not only after the operation. This procedure must be performed by a qualified plastic surgeon.
