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

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

From the beginning, Engelberg shows the struggle between the life threatening nature of cancer and dealing with

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

I got my research topic idea from my uncle having Ependymoma. I only knew a few things from hearing doctors, surgeons, and my parents talk about it. I did a lot of research to find out all the information I did. While writing this paper my mom also reminded me that my second cousin had this type of brain cancer since he was two years old. I didn’t mention him in my paper because I don’t have as much of a connection to him as I do my uncle. His name was Ryan and he recently passed away of age 8 on Monday.

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

In regionally heterogeneous neoplasms such as astrocytomas and pineal germ cell neoplasms, the small size of the specimen creates theoretical problems. Here the diagnosis depends not only on obtaining abnormal material and the pathologic interpretation but also on regional differences within the neoplasm. Two solutions are available at stereotactic biopsy to overcome this problem. The first is to take several specimens from different target points in the lesion, increasing the tissue volume to provide a representative sample.

The cancer cells that develop in the nerve tissues may vary and require different forms of treatments depending on its location and stage. After the detection of Neuroblastoma, various methods of testing are performed to identify where the cells have caused dysfunction and where they have

Pheochromocytoma is a term used to refer to rare and mostly benign catecholamine-secreting tumors arising from the chromaffin cells found in the adrenal medulla or in the paraganglia (i.e. extra-adrenal pheochromocytoma). Clinical presentation can be highly variable and can mimic other diseases, but the condition typically presents with hypertension, palpitations, severe headaches and sweating.

It is cancer that occurs in the adrenal glands when abnormal cells form in the gland or travel from another part of the body. It normally happens in the outer layer called the adrenal cortex. It forms as a tumor and can be either benign, which is not cancerous, or it can be cancerous. When it's a benign tumor, it is called benign adenomas. A cancerous tumor of the adrenal glands would be called an adrenal cortical carcinom. in 1886 Felix Frankel was the first person to say that someone had an adrenal tumor

Neuroblastoma is a type of cancer. Cancer is when cells grow out of control, join together, and form a tumor. Neuroblastoma tumors start in cells in the nerves. The cancer can then spread to other parts of the body. Most often, tumors are found in the abdomen, the glands that make hormones, and on top of the kidneys (adrenal glands).

• Neurological symptoms include excessive blood vessel growth on the surface of the brain (angiomas). These angiomas are typically located on the posterior or occipital

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,

The majority of tumors (60-70%) in pediatric age group occur in the posterior fossa. The reason behind propensity to occur in the posterior fossa has not been elucidated till date. Lesion in the posterior fossa may be neoplastic, developmental and vascular processes requiring surgical intervention. By far, the most common posterior fossa tumors of childhood are medulloblastomas, ependymomas and astrocytomas. Medulloblastomas are the most common malignant brain tumor in children comprising 20% to 25% of all pediatric brain tumors. The median age at diagnosis is approximately 6 to 9 years. Most of tumors occur in midline and frequently found associated with hydrocephalus. Success with surgical intervention has become possible because of improved understanding of physiology, advances in imaging and microsurgical techniques, excellent anaesthetic techniques available, advances in perioperative care of the patient. These in turn have improved the survival and quality of

When I was 17 years old, my father was diagnosed with a brain tumor. Without a doubt it was an event which marked my life and helped me mature in many aspects. I witnessed how my father began to lose his cognitive functions like his ability to focus, changes in his personality, behavior and emotions. This was the first time that I felt interested in learning how the brain process the information and motivated to learn more regarding this disease in order to help him. After my father passed away, my mother fell into a depression so I began to search for ways to improve her emotional state by reading books and magazines on the subject.
