    How to diagnose Benign schwannoma ?
    ### Response:
    Is genetic testing available for schwannomas? Genetic testing is not available for many individuals with schwannomas since most of these tumors occur sporadically (by chance) and are not caused by a genetic mutation. However, genetic testing is an option for people with an inherited condition that predisposes to schwannomas such as certain types of neurofibromatosis (neurofibromatosis type 2 and schwannomatosis).
