Are brain tumors hereditary?
There are some brain tumors that are hereditary but the majority are not. As of yet, there aren’t any known causes for brain tumors. Research is being conducted to further prove any hereditary links. Certain diseases like neurofibromatosis predispose people to brain tumors of the cranial nerves, such as an acoustic neuroma tumor. With metastatic brain tumors, the original, or primary, cancer may be hereditary, but the actual spread of the tumor to the brain is not.
