    What are the treatments for Intravenous leiomyomatosis ?
    ### Response:
    How might intravenous leiomyomatosis be treated? The mainstay of treatment for IVL is surgery to remove the tumor and its spread throughout the body. The use of anti-estrogen therapy, such as tamoxifen, has also been suggested. Surgery requires the complete removal of the tumor, since incomplete removal may result in a recurrence and hence further surgery or even death.
