Uterine fibroids combined with adenomyosis indicates the presence of two diseases of the uterus, one is a benign tumor, i.e. fibroids, and the other is adenomyosis. Adenomyosis is a disease caused by the growth of the endometrium in the uterine muscle tissue, and the main symptom is dysmenorrhea, which means that each menstrual period is more painful than the previous one, and the pain is more severe and unbearable. It can also lead to increased menstrual flow and even heavy bleeding. That is why surgical treatment is recommended in the presence of uterine fibroids and adenomyosis, where the fibroids are removed. Adenomyosis can also be properly removed from the lesion, but since there is no clear boundary for adenomyosis, only part or most of it can be removed, and there will be residuals. Surgery can be followed by intramuscular injections of leuprolide or goserelin, which will help the lesions to subside, or by treatment with a menstrual ring.
