Primary Brain Cancer

Brain tumors can be a cause of seizures also, but these are very rare. Most epileptic patients have been tested for brain tumors, just

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).

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.

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

Primary brain tumors start in the brain tissue and they are classified by the type of tissue that they occur in. Gliomas are the most common type and they occur in glial tissue. Gliomas are further broken down into Astrocytomas, Oligodendrogliomas, and Ependymomas. Astrocytomas come from small cells in the shape of a star called astrocytes. These tumors can grow in any place on the spinal cord or in the brain. For adults, the most often form in the cerebrum and for children they form in the cerebrum, cerebellum and brain stem. There are different grades to the tumors and they have different names depending on grade level. Oligodendrogliomas are produced in cells that have myelin. These tumors usually occur in the cerebrum. Additionally, they are slow to grow and do not spread. Ependymomas form in ventricles' lining and can also grow in the spinal cord. They commonly occur in childhood and adolescence but like all tumors can occur at any

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

An Astrocytoma is a type of tumor that is created by star-shaped cells called astrocytes. These astrocytes are the largest and most numerous type of neuroglia in the Central Nervous System, and make up the supportive tissue of the brain. Because of the size and number of astrocytes they are the most common Central Nervous System tumor. Although Astrocytomas are so common, the cause remains unknown. Researchers believe that genetics could be a part of the cause of Astrocytomas. Astrocytes combine with other support cells called Oligodendrocytes and Ependymal cells to make up glial tissue. Tumors within the glial tissue are referred to as gliomas. This means that an Astrocytoma is a glioma tumor, and can be broken down into four grades or levels based off of how aggressive the tumor is.

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

Gliomas are the most common type of primary brain tumor, accounting for 10-20% of its total. (5,19–21). Histopathology pattern is the most important feature in glioma classification. (22) The 2007 WHO classification of tumors of the central nervous system divides gliomas into four main types, with increasing degree of malignancy (from I-IV). Low-grade gliomas are defined a grade I and grade II, in opposition to the “high-grade gliomas”, WHO grade III and IV. The so-called “diffuse low-grade gliomas” integrate 2007 WHO II class, and include diffuse astrocytomas, oligodendroglioma and oligoastrocytoma (mixed glioma) (19). There are some pertinent critics to this grading system, such as the great inter-variability among neuropathologist experts. More importantly, 2007 WHO grading doesn’t contemplate the continuum between grade II and III. In fact, many DLGG has an “intermediate” behavior, with some more aggressive microfoci lodged in the core of the neoplasm (19,23,24). Hence, the term diffuse low-grade glioma is preferred in this article.

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

Recent studies including a genome-wide study of certain cancers have come to demonstrate that the most common and most aggressive type of brain malignancy, or glioblastoma (GBM) comprises a shared link: alterations in the catalytic protein, isocitrate dehydrogenase (IDH) (1). The focus of such research is the mutant forms of NADP-dependent homologous enzymes IDH1 and IDH2 (2) - localized predominantly in cytosolic and mitochondrial regions, respectively. Both of these heterozygous point mutations modify the amino acid residue present at the active site of the original enzyme. Subsequently, neomorphic activity of the enzyme IDH is established, replacing its original function with the conversion of the α-Ketoglutarate (α-KG) to D-2-hydroxyglutarate (D-2-HG), an oncogenic metabolite (3). The presence of IDH1/2 mutants in cells is consistent with abnormally high levels of this tumor progressor, D-2-HG, which inhibits catalytic proteins that are α-KG-dependent (4). As a result, D-2-HG indirectly influences epigenetic regulation, the formation of collagen as well as histone methylation. Transgenic mouse models are now advancing to provide insight into the effects of IDH mutations in tandem with other cooperating mutations better understand glioma pathogenesis (5).

Neuroblastoma most often begins in early childhood. It usually affects children under the age of five. It is found when the tumour begins to grow and cause symptoms. Sometimes the tumour forms before birth during the growth of the fetus whilst in the womb. This tumour is found during a fetal ultrasound. Neuroblastoma often begins in the abdomen affecting the nerve tissues of the adrenal gland. There are two adrenal glands, positioned one on top of each kidney in the back of the upper abdomen.

Among the many types of cancer that can affect children, Neuroblastoma is very rare, yet it is the most common extracranial (located on the outside of the cranium) tumor in infants. It mostly affects children of five years and younger. Neuroblastoma is a kind of cancer that develops from neuroblasts (immature nerve cells). It usually appears around the adrenal glands in the kidneys, but might also be found in the chest, spine, abdomen, and neck.

Benign tumors are non-cancerous and do not invade nearby tissue. On the other hand, malignant tumors are cancerous and spread to other parts of the body. Judging by the fact, Renee had a difficulty speaking, and was unable to remember her way back home, it seemed like both frontal lobe and temporal lobe of brain were affected by tumors. Since she cannot remember where she lived, it is likely tumor was suppressing the hippocampus area, where long-term memory is stored. Also, Brocas’s area seemed to be affected by tumor since she had trouble with speaking words. As a health-care professional, I will explain to the family member how the brain tumor may affect the patient’s cognitive, mental, memory, and language ability. Also, I will encourage

The brain is made up of millions upon millions of cells. These cells are formed from before birth, up until about 7 years old. Once these brain cells stop dividing, they are never meant to divide again. You can see that the division of brain cells is under strict regulation and control. When this control is lost in a single cell, then it starts dividing in an uncontrolled manner. All of the data obtained through research on cancer shows that this disease is caused by a rapidly dividing cell, with no regulators to stop it from dividing. As the cell makes more and more copies of itself, it grows to form a tumor. This is known as cancer.
