Brain Tumors Research Paper

Primary brain cancer develops from cells within the brain. Part of the central nervous system (CNS), the brain is the control center for vital functions of the body, including speech, movement, thoughts, feelings, memory, vision, hearing and more.

Central neurocytoma is a rare tumor that affects young adults. Neurocytoma is characterized with its high reoccurrence rate after surgical resection. Unfortunately, the molecular cell origin of neurocytoma remains unknown till further investigation. Current and past studies has showed different genetic variations and reasons for the tumor that ranges from over expressed oncogenes like N-MYC and insulin factor growth 2, Platelets derived growth factor D and neuregulin. The tumor often involves the lateral ventricle of the brain. The current classification of brain tumors is centered on two theories, the first theory uses the phenotypic morphology of the tumor as an indicative of its origin.

However, even benign tumors have a risk of causing damage to the brain through either compression or infiltration.

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.

Primary brain tumors begin when normal cells develop errors or mutations in their DNA. These mutations allow these cells to grow and divide at faster rates causing a result in a mass of abnormal cells that form a tumor. Secondary brain tumors are more common than primary brain tumors and most often occur in people who already

Examples of this would be meninges which are the brain-covering membranes. Cranial nerves, pituitary gland, and pineal gland are all other examples. Cranial nerves are nerves that directly go to your brain. Pituitary glands are glands that control your hormone glands. Pineal glands are in the vertebrate of your brain. There are primary and secondary brain tumors. Primary begins when normal cells get mutations in their DNA. Mutations let cells grow and go separate ways as the rates are increasing. A mass of abnormal cells is the result of this and forms a tumor. You might not have heard of primary brain tumors as much as secondary brain tumors. Secondary brain tumors begin to spread elsewhere in the brain (Mayo Clinic Staff 2,

The specific cause of Anaplastic Astrocytomas is unknown. However, researchers believe that genetic and immunologic abnormalities, environmental factors (e.g., exposure to ultraviolet rays, certain chemicals, and ionizing radiation), diet, stress, and/or other factors may play contributing roles in causing specific types of cancer. Astrocytomas are more common amongst individuals that have these genetic disease: tuberosis sclerosis, neurofibromatosis, & Li-Fraumeni syndrome. In the case of these rare genetic disease the brain tumor is not passed to the child (Cheong,

Brains Tumours: Cancer By Finlay McKibbin oGe3 Which part of the bedy dees it affect? Brain tumours effect the brain, being formed in its glial cells, which grow from the supporting cells of the brain These tumours are known as "gliomas. Considering they develop in the brain, they are formally known as primary brain tumours. Also, the part of the brain the brain tumour effects, changes the symptoms and treatments for the individual. Common Symptoms. The common symptoms of brain tumours are; Headaches: being the most common symptom, being both severe and persistent in few cases, and can come or go Seizures Nausea and vomiting Difficulty when speaking or being able to recall words Disturbed vision, hearing, smell, and or taste Weakness and or

Brian tumors are a collection of abnormal cells in the brain. They can be either cancerous(malignant) or non cancerous(benign). Either way they still have to be treated because brain tumors are painful. The pressure in the brain increases which causes brain damage or death. So its pretty important to treat them as soon as possible.

The most aggressive classify as malignant. The less aggressive acquire the name benign. Tumors stand classified by the aggressiveness of the tumor. The most malignant tumor would classify as Grade IV. The less malignant would classify as Grade I. There are 120 different brain and nervous system tumors (Tumor). A term usually used for malignant tumors is cancer. The malignant tumors spread fast and take over healthy cells for blood, space, and nutrients. Benign tumors spread slowly or do not spread at all. They remain less serious than malignant but can cause symptoms. They could cause pressure on a certain part of the brain and cause it to malfunction (Brain Tumors

Glioma is the most common form of central nervous system (CNS) neoplasm that originates from glial cells. In the United States, there are six cases of gliomas diagnosed per 100,000 people every year. Gliomas are very diffusely infiltrative tumors which affect the surrounding brain tissue. Glioblastoma is the most malignant type while pilocytic astrocytomas are least malignant brain tumors. In the past, these diffuse gliomas were classified into different subtypes and grade based on histopathologically such as a diffuse astrocytoma, oligodendrogliomas, or as mixed gliomas/oligoastrocytomas. Recently, gliomas were classified based on molecular and genetic markers. These advances have more specific prognostic and therapeutic benefits for patients

In 2010, 1680 brain and CNS cancers were diagnosed in Australia and 1250 deaths occurred as result of brain and CNS cancers. The risk of being diagnosed with brain and CNS cancer by age 85 is 1 in 95 for men and 1 in 152 for women, the risk of death from brain and CNS cancer by age 85 is 1 in 124 for men and 1 in 193 for women (AIHW, 2014). Brain and CNS cancers include primary tumours, which start in the brain or the

Brain Tumors- Most common cancer in childhood and occur in 25% of all childhood cancers. Neoplasms can come from any cell, which means tumors can form in all different areas of the brain. Tumors can be benign or malignant. Clinical manifestations of brain tumors are directed towards the affected area. Most common symptom is a headache and vomiting. Neurological changes, behavioral changes, cranial nerve neuropathy and vital sign disturbances may occur depending on the location of the brain tumor. Diagnosis is based on the symptoms the patient presents with. CT and MRI are most commonly used. Tissue specimens are collected and tested. Results help with the diagnosis. Treatments include surgery, chemotherapy and radiotherapy. Not all have to

Glioblastoma is the most deadly form of brain cancer, accounting for over 15,000 deaths in 2015 alone, and is responsible for 52% of all primary brain tumors. There are 2.96 cases of glioblastoma for every 100,000 people. Glioblastoma is so fatal because it does not react to normal cancer treatments like radiation therapy, chemotherapy, and surgery the same way that other cancers do.

A brain tumor is a collection (or mass) of abnormal cells in the brain. The skull is very rigid and the brain is enclosed, so any growth inside such a restricted space can cause problems. Brain tumors can be cancerous or non-cancerous. When benign (non-cancerous) or malignant (cancerous) tumors grow, they can increase the pressure inside the skull. This can cause brain damage and even death. Radiologists examine the patient physically by using Computed Tomography (CT scan) and Magnetic Resonance Imaging (MRI). These medical are used in surgery, irradiation planning and tumor treatment. Figure 1 shows MRI image. It shows that tumor tissues are brighter than normal tissues. To segment the tumor is challenging
