    ### Response:
    Are anaplastic astrocytomas inherited? Anaplastic astrocytomas are usually not inherited. These tumors typically occur sporadically, in people with no family history of astrocytomas. In most cases, the exact cause is unknown. Familial cases of isolated astrocytomas have been reported but are very rare.
