When the endometrial glands and mesenchyme invade the myometrium, it is called adenomyosis, which is a benign disease but is known as the “undead cancer” because it causes unbearable pain and, even worse, there is no specific medical treatment for it, but only temporary control. The disease is only temporarily controlled. Treatment for this disease is determined by the age and symptoms of the patient. In young patients with dysmenorrhea, symptomatic treatment is given and non-steroidal anti-inflammatory drugs are taken for pain relief; patients who are near menopause can also be treated conservatively; if the patient has no reproductive requirements, has chronic severe pain, conservative treatment is ineffective and is old, total hysterectomy should be performed, whether the ovaries are preserved depends on the age of the patient and the condition of the ovaries; for patients with relatively limited lesions and young patients with reproductive requirements, focal resection can be performed For patients with limited lesions and young fertility requirements, focal resection can be performed. In addition, presacral neurectomy can be used to relieve dysmenorrhea. There are no effective drugs to cure this disease, and the progestins, Mannitol, GnRH-a, oral contraceptives, Danazol, etc. used in clinical practice are only symptomatic treatment, and discontinuing them requires facing the risk of disease recurrence. Therefore, for this disease, unless hysterectomy or natural menopause, other treatments are only expedient measures to temporarily relieve symptoms and relieve pain.
