    What are the treatments for Cavernous Malformation ?
    ### Response:
    The primary treatment option for a CCM is surgical removal. Radiation therapy has not been shown to be effective. The decision to operate is made based upon the risk of approaching the lesion. For example, symptomatic lesions close to the brain surface in non eloquent brain (areas for example, those areas not involved with motor function, speech, vision, hearing, memory, and learning) are very likely to be candidates for removal.
