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 ...
Malignant brain tumor types About 78% of malignant brain tumors in adults are gliomas (pronounced glai-ow-muhs). These start in your glial cells, which are the cells that give structural support to the other cells in your brain. Glial cells include astrocytes, ependymal cells, and oligodendro...
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 Brain cells Ner...

Small vessel disease burden and risk of recurrent cerebrovascular events in patients with lacunar stroke and intracerebral haemorrhage attributable to deep... Discussion/Conclusion: DPA manifesting as ICH is associated with more severe MRI SVD burden and worse outcome compared to LS. The short-term ...
The three most common types of brain tumour are intracranial metastases, which spread from other primary sites of disease; meningiomas, which are mostly benign; and glioblastoma multiforme (GBM), which is the most common and lethal primary malignant brain tumour in adults. Median survival in GBM ...
Glioblastoma multiforme (GBM) is a highly aggressive brain tumor that can evade the surveillance mechanisms of the immune system, making it difficult to treat. The type 2 immune response is a complex mechanism that can be either beneficial or detrimental to cancer growth, depending on the context...
In addition, the main etiologies of increased T2-relaxation values in the brain are vasogenic edema, demyelination, gliosis, or neuronal loss [17,18,19], observed in tumor [20], chronic epilepsy [21], congenital central hypoventilation syndrome [22], traumatic brain injury [23], and ...
Here, we will first examine sex differences in brain tumors. We will present data regarding the predominance of cases in males for most individual tumor types and consider the lessons of exceptions like meningioma and low-grade astrocytoma. Second, we will review the developmental and evolutionary ...
other groups have demonstrated that brain somatic mutations arising from the ventricular or subventricular zone, a well-known neural stem cell niche in the human brain, lead to various childhood or adult neurological disorders, including cortical malformations, intractable epilepsies, and brain tumor4,5...
