    ### Instruction:
    What are the treatments for Von Hippel-Lindau Disease (VHL) ?
    ### Response:
    Treatment for VHL varies according to the location and size of the tumor. In general, the objective of treatment is to treat the tumors before they grow to a size large enough to cause permanent problems by putting pressure on the brain or spinal cord. this pressure can block the flow of cerebrospinal fluid in the nervous system, impair vision, or create deafness.
