Glioblastoma Multiforme (GBM), also known as a grade IV astrocytoma, is the most common and most aggressive type of primary brain tumor. Although GBM can occur at any age, the disease is most commonly diagnosed after the age of 50.
I wanted to discuss this type of cancer and add it to the Cancer by the Numbers feature because it has directly affected my family. My 39-year-old uncle died of the disease in 1987. He only survived a year after diagnosis. It is disheartening that this disease has not seen any strides in improved survival rates over all these years.
The Numbers
GBM accounts for 52 percent of all primary brain tumor cases. Brain tumors account for one in every 100 cancers diagnosed annually in the United States. Most malignant brain tumors and brain cancers have spread from other tumors in the body to the skull, including cancers of the breast and lung, malignant melanoma and blood cell cancers.
