Synonyms Neoplasm Definition A brain tumor is a mass of abnormal cells. There are two broad categories of brain tumors. Primary brain tumors arise from an abnormal proliferation of cells within the central nervous system (CNS). In contrast, metastatic tumors originate elsewhere in the body and ...
Most of the time, doctors can’t tell what causes a brain tumor. There are only a few known risk factors for brain tumors in adults. Exposure to radiation. Children who receive radiation to the head have a higher risk of getting a brain tumor as adults. Family history. Some brain tumors...
Glioblastoma is the most common type of brain tumor in adults. The disease is 100% fatal and there are no cures, making it the most aggressive type of cancer. Such a poor prognosis has motivated researchers and neurosurgeons to understand the biology of tumors with the goal of creating bette...
ImportanceMalignant primary brain tumors cause more than 15 000 deaths per year in the United States. The annual incidence of primary malignant brain tumors is approximately 7 per 100 000 individuals and increases with age. Five-year survival is approximately 36%. ObservationsApproximately 49% o...
Aprimary brain tumorhas its origin in the brain itself. These tumors can be benign or malignant. In adults, meningiomas and gliomas are seen as the most common types of tumors. These tumors can develop from your brain: The membranes that envelop your brain, known as meninges ...

Glioblastoma is the most common malignant brain tumor in adults. Roughly five in every 100,000 people develop this type of cancer each year. The diagnosis amounts to a death sentence: Even after surgical resection followed by radiation and chemotherapy, the glioblastoma will kill the patient in ...
Among them, glioblastoma multiform (GBM) is the most common malignant primary brain tumor in adults with a poor prognosis of 5-year survival rate less than 5% following the standard therapy. In the past 17 years, the standard therapy of GBM has been surgery followed by radiation and the ...
The clinical difference between brain tumors in adults and children is striking. Compared with adults, pediatric tumor types (mostly glial and neuronal) are more sensitive to adjuvant irradiation and chemotherapy. Pediatric tumors more often require craniospinal irradiation based on their propensity to ...
Scientists studying the most common and aggressive type of brain tumor in adults have discovered a new way of analyzing diseased and healthy cells from the same patient. Crucially, the work which has been funded by the charity Brain Tumor Research could pave the way for truly personalized treatme...
