In the earlier times, endometriosis was considered the disease of women in reproductive age. But the latest statistics shows that it occurs more and more often in women during their menopause. Hardly it is the change of the tendency, perhaps such data are connected with the improvement of the diagnostic methods. In the menopausal period, it is very difficult to diagnose endometriosis because of the rebuilding of hormonal systems and multiple changes in her organism. The earlier the disease is diagnosed, the easier it will be endometriosis treatment. Menopausal endometriosis is especially dangerous because the disease in this period may have serious consequences for a woman.
