Whether or not adenomyoma is serious depends on whether or not it causes symptoms.
In patients with adenomyosis, the endometrium that is ectopic to the myometrium with each menstrual period will also hyperplasia, exfoliate and bleed in response to the estrogen and progesterone cycle, but this bleeding is inside the myometrium, causing the uterus to enlarge. If the ectopic endometrium is confined to one part of the myometrium, the monthly bleeding will cause hematoma and mass, which is called adenomyoma.
Uterine adenomyoma is mostly a benign disease. The clinical manifestation is secondary to dysmenorrhea, which progressively worsens and may even be unbearably painful, and may also lead to heavy menstrual flow and anemia.
Uterine adenomyoma is a benign disease, but if serious symptoms appear, the condition is relatively serious, and must be under the guidance of a doctor to regulate the treatment, so as to avoid delaying the condition.
