👉 A leiomyoma, also known as leiomyosarcoma, is a type of benign tumor that occurs in the lining of the uterus and ovaries. It is characterized by the growth of smooth muscle cells, which can lead to abnormal tissue growth and may cause symptoms such as pain or discomfort during menstruation or during sexual intercourse. The exact causes of this condition are not fully understood, but it is thought to be related to an imbalance in hormones that affect the reproductive system.
