Leiomyoma is a type of benign tumor that arises from smooth muscle tissue. These tumors are most commonly found in the uterus, where they are often referred to as uterine fibroids. They can vary in size and may cause symptoms such as heavy menstrual bleeding, pelvic pain, or pressure on nearby organs. Although leiomyomas are non-cancerous, their presence can lead to complications depending on their size and location. Treatment options include monitoring, medication to manage symptoms, or surgical procedures to remove the tumors if they cause significant issues. Regular check-ups can help in managing any potential problems.
