The word glioma itself typically means that this tumor is coming from the brain, as opposed to coming from somewhere else in the body and having spread to the brain.
Her research has focused on the development of the mammalian brain, and particularly on why a malignant and quick-spreading kind of brain tumor called glioma is so deadly.
In 2004, a rash of early scientific reports suggested that cell phones, which produce radio frequency energy, might cause a fatal form of brain cancer called a glioma.
The prognosis is very dim for people who get this type of malignant glioma, which is what he had.

DANIEL BARROW, NEUROSURGEON: Well, a glioma is a tumor that arises from the brain tissue itself.
In Interphone, men and women with a variant of brain cancer called glioma were asked to recall their level of exposure to cellphone radiation.
"There was weak evidence of an association between mobile phone use and risk of brain tumours,but any evidence of increased risk was not more evident in the temporal lobe temporal glioma, which is the area that is most exposed to mobile phone radiation and where you would expect to find evidence of an association, nor in people who had held subscriptions for the longest time," he said.
During a news conference, Dr. Samet said the panel's decision to classify cellphones as "possibly carcinogenic" was based largely on epidemiological data showing an increased risk among heavy cellphone users of a rare type of brain tumor called a glioma.
One exception is a 2010 study that found a slight, statistically insignificant increase in risk in a rare form of brain cancer called glioma among cell phone users.
