My mother has recently been diagnosed as having a glioblastoma. I wonder if you could suggest a source for information regarding genetic causes. I had an uncle die from the same tumor eight months ago. Can you make any suggestions?
With Kind Regards,
Nancy J. O'Connor, RN, MSN, CRNP, of the Brain Tumor Center at the University of Pennsylvania Hospital responds:
Overall, there are no known causative factors or known hereditary risks associated with the development of glioblastoma multiforme. There are hereditary diseases, Von Hippel Lindau and neurofibromatosis, that have an associated risk with the development of brain tumors but these are very rare. Areas that are being looked at as possible causes include viruses, genetic defects, and occupational factors such as working with electromagnetic fields or in the petrochemical industry.
