ON THIS PAGE: You will find out more about what factors increase the chance of astrocytoma. To see other pages in this guide, use the colored boxes on the right side of your screen, or click “Next” at the bottom.

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 don’t know what causes most childhood tumors. There is some evidence that genetic factors may play a role in a small percentage of children with cerebral astrocytoma. For example, children who have neurofibromatosis may have an increased risk of developing astrocytoma. Neurofibromatosis is an inherited disorder that causes neurofibromas (a type of noncancerous tumor) to form on peripheral nerves in the body, brown spots on the skin, and tissue and bone deformities. Neurofibromatosis is also called Recklinghausen’s disease or von Recklinghausen’s disease. Learn more about neurofibromatosis type 1 and neurofibromatosis type 2. Other, less common genetic conditions associated with a higher risk of CNS tumors include Li-Fraumeni syndrome, tuberous sclerosis, nevoid basal cell carcinoma syndrome, and Turcot syndrome.
