A risk factor is anything that increases a person’s chance of developing a tumor. Although risk factors often influence the development of a tumor, most do not directly cause a tumor. Some people with several risk factors never develop a tumor, while others with no known risk factors do.
Doctors and researchers do not know what causes most childhood tumors. There is some evidence that genetics may play a role in a small percentage of children with cerebral astrocytoma. The following factors may increase a child’s risk of developing astrocytoma:
Neurofibromatosis. Neurofibromatosis is an inherited disorder that causes a type of noncancerous tumor called a neurofibroma. Neurofibromatosis is also called Recklinghausen’s disease or von Recklinghausen’s disease. Learn more about neurofibromatosis type 1 and neurofibromatosis type 2.
Other genetic conditions. Less commonly, the following genetic conditions are associated with a higher risk of developing a central nervous system (CNS) tumor:
