A brain tumor or intracranial neoplasm occurs when abnormal cells form within the brain.
Glioma is a type of tumor that starts in brain or spine and raises the glial cells, which causes the gliomas. These cells are mostly responsible in making the tumors in brain. These cells are malignant in nature. Hereditary genetic disorders such as neurofibromatosis and tuberous sclerosis complex are known to predispose to their development and existance. Gliomas have been correlated to the electromagnetic radiation and most of the glioblastomas are infected with cytomegalovirus, which speeds the development of tumors. Some genetic disorders also increase the risk of development of gliomas tumors in children but rarely in adults. The tumor growth exist for more growth and final death occurs within 2 to 3 years.
Review articles are the summary of current state of understanding on a particular research topic. They analyze or discuss research previously published by scientist and academicians rather than reporting novel research results.
Review article comes in the form of systematic reviews and literature reviews and are a form of secondary literature. Systematic reviews determine an objective list of criteria, and find all previously published original research papers that meet the criteria. They then compare the results presented in these papers. Literature reviews, by contrast, provide a summary of what the authors believe are the best and most relevant prior publications.
The concept of "review article" is separate from the concept of peer-reviewed literature. It is possible for a review to be peer-reviewed, and it is possible for a review to be non-peer-reviewed.
