Primary Brain Tumors

When a tumor is developed on the brain, it is called a brain tumor or brain cancer. Brain tumors can be

Glioblastoma (pronounced like gleO blastoma) is an incurable brain cancer,Survival rate is usually measured in months.This became a word that was instantly defined, researched, dissected, feared, and tried to comprehend and understand by family,friends and acquaintances of Larry McKee (McKee)who was personally affected from this single word, it was quickly added to their vocabulary, because of the of the events that transpired on October 22, 2011 that forever changed lives “Glioblastomas are tumors that arise from the astrocytes- the star-shaped cells that make up the “glue-like,” or supportive tissue of the brain. These tumors are usually highly malignant (cancerous) because the cells reproduce quickly and they are supported by a large network of blood vessels.”(A.B.T A..) He was diagnosed with stage four.

The primary ones include these types. Gliomas, the most common brain tumor involving the brain tissue. There are different grades and even types of gliomas. But if the tumor grade is higher, it will probably grow faster. Medullblastomas are brain tumors that in young children. Without treatment it will spread rapidly into the spinal fluid and other parts of the brain. But almost or half of the brain tumors found are benign. These types of brain tumors are usually Meningiomas and Neuromas. Meningiomas begin in the tissue membranes. Neuromas are in the nerves mostly in people over

Tumors can be classified into three types: 1) benign 2) pre malignant 3) malignant tumor. Benign tumors are those which are incapable of abrupt expanding and affecting the other healthy brain tissues. Premalignant tumor is a pre cancerous stage, if not treated properly it may lead to cancers. It is often considered as a disease. Malignant tumor grows rapidly with time an ultimately leads to death of patient. Malignant is a medical term describing a sever growth of a disease. The most common primary brain Tumors are gliomas, wherein 70% are in the group of malignant gliomas, glioblastoma multiform (GBM).The GBM is one of the highest malignant human

Glioma is a tumor that is a type of brain cancer. Glioma tumors are made up by cells called glial cells. Glial cells normally provide nutrition, oxygen, and structural support to the brain. Three types of glial cells can produce tumors. Gliomas are named after the type of glial cell that is involved in the tumor. A tumor is formed when the glial cells grow into an abnormal mass of tissue. Gliomas are one of the most common types of brain tumors that occur in adults.

Gliomas are the most common type of primary brain tumor in adults and a critical cause of cancer mortality. According to the World Health Organization, gliomas classified into four grades, which are determined by the pathologic evaluation of the tumor. Low-grade gliomas (grades I and II) and high-grade gliomas (grades III and IV).

An Intracranial tumor is an irregular group of brain tissue in which cells widen and cultivate intractably, which effects the means to control normal cells. Intracranial tumors situated in the frontal lobe are quite natural since this lobe is the biggest in the brain. These growths are categorized as primary, which means they start out in the brain (benign), or secondary, meaning they have a different starting location in the body and spread to the brain (metastasized). Primary tumors tend

CNS tumors represent the second most frequent tumor of childhood and the most common pediatric solid tumor; approximately 2,200 patients under the age of 20 are diagnosed each year with invasive CNS tumors, and CNS tumors are the number one cause of death from childhood cancer. [1] Therapeutic strategies generally involve surgery as a primary intervention, but complete resection is often not possible due to tumor location. In such cases, adjunct therapies, including chemotherapy and radiation therapy, may be required based on the tumor histology and presence of residual tumor. [2]

What is Cancer? Cancer is many diseases which involve abnormal cell growth. Cancer cells are able to replicate and spread because they completely lose control and are not able to be restrained. These cells will then form to become tumors. There are two types of tumors called malignant and benign. The malignant tumor is the cancerous tumor. The benign tumors are much less destructive to the body. To tell the difference is quite simple, a malignant tumor has the ability to spread through metastasis causing the cancer to attack multiple areas, whereas the benign tumors cannot spread and are in most cases nonthreatening. Although there are numerous types of cancer, such as breast cancer, lung cancer, and kidney cancer, I chose to write about brain

that the more of the tumor that is removed the better the prognosis. The major thing that

Gliomas are primary brain tumors, which mean they start in the brain. They are a fairly common type of brain tumor. These types of tumors originate in the glial cells. Glial cells in the brain surround and support neurons. Because Gliomas often intermix with normal brain tissue, they are called intrinsic brain tumors. Gliomas show up in three different types of cells: astrocytes, oligodendrocytes and ependymal cells. Astrocytomas will be produced by an astrocyte, an oligodendroglioma will be produced by an oligodendrocyte and epedymomas will be produced by an ependymal cell. If there is a mixture of these cells, then it is called a mixed

Current investigations indicate that Central neurocytoma could be of astrocytic origin or mixed lineages. Immunohistochemical tests shows multiple positive markers of neural cell that includes synaptophysin, neuron specific enolase, neuronal specific nuclear protein , and neuron specific class III beta tubulin. In addition to dense core vesicles and parallel microtubules are present in pathology. The tumor also shows positive neurofilament (NF) staining but some of the Central Neurocytoma fails to show consistent pathology. Unfortunately, the Immunohistochemical studies are not specific to draw a concrete conclusion to the origin of neurocytoma. Von Deimling et al. investigation indicated that Central neurocytoma shows glial fibrillary acidic protein (GFAP) and Syn, which is related to reactive astrocytes. Other studies were unable to attain the same results. In vitro, the tumor cells tend to become glial cells regardless of the medium of the culture. In vivo, the origin of the cells is not clear. Some researches hypothesize that CN arise from neural stem cells surrounding the ventricle zones. This hypothesize was based on high levels of choline, cholinergic receptors, gamma-aminobutyric acid, and normal or low levels of glutamate and catecholamines. Kim et al also showed the presence of Musashi-1, and the neuroep- ithelial enhancer gene nestin. These results point towards possible genetic properties to

A brain tumor is a mass or development of irregular cells in your cerebrum or near your mind. There are different types of brain tumor exist which even are health hazardous. Essential brain tumors rise up out of the different cells that make up the cerebrum and focal sensory system and are named for the sort of cell in which they first shape. Gliomas and astrocytic tumors are the most common types of adult brain

Glioblastoma multiforme (GBM) is the most prevalent and aggressive primary brain cancer, accounting for about half of all malignant primary brain tumors.

Common malignant brain cancers increase significantly according to statistical data collected by the National Cancer Institute. In 1984, the annual incidence rates of primary brain tumor and primary brain lymphoma also increased notably, the rate of lymphoma almost tripling,
