Is glioblastoma hereditary?

Rarely: Glioblastoma can rarely occur as an inherited cancer in patients with certain familial cancer syndromes such as li fraumeni syndrome, turcot syndrome, neurofibromatosis or familial glioma syndrome. Family members may have increased risk of glioblastoma due to environmental factors also.

While there may: Be some tell-tale genetic fingerprints on some glioma, the bad one, gbm seems to be sporadic, with only radiation exposure as a risk. My father died of one 30 years ago. No other family members have had any brain tumors.

No: There is no evidence of heredity in Glioblastoma. Joshua Garren, MD Medical Director, Tulsa Brain Tumor Clinic braintumorclinic.org
