Gynecomastia is the enlargement of the male breast as a result of the growth of glandular, fibrous and adipose tissue. There are two types of gynecomastia- transient, associated with puberty and usually disappears and pathological, associated with various types of disease. Very often occurs with thyroid diseases, hormonal fluctuations or obesity. The procedure of removing overgrown mammary glands is particulary important due to the patient's psyche. In most cases, this disease causes not only an aesthetic defect, but also a sense of shame, increasing alienation, lack of acceptance of the body and a sense of masculinity.
