Primary Brain Tumors Essay

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

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]

When cancer develops elsewhere in the body and spreads (metastasizes) to the brain, it’s called a secondary brain tumor, or metastatic brain cancer. Metastatic brain tumors are more common than primary brain tumors. Some cancers that commonly spread to the brain

Neuro-Oncology is the study of cancer in the brain, skull base, or spinal cord. They can also treat genetic disorders of a certain type such as Neurofibromatosis. Neurofibromatosis is tumors that grow in the nervous system that is caused by a genetic disorder. The main purpose of the research was to gain information on Neuro- oncology, general information on brain tumors, and general information on specific tumor types. Central nervous system tumors include various gliomas such as glioblastoma multiforme, astrocytoma, brainstem glioma, ependymoma, and oligodendroglioma. Furthermore, meningioma and vestibular schwannomas. Other conditions neuro-oncologist can treat are central nervous system lymphoma, metastic disease to the spine

On April 14, 2012, my husband was diagnosed with a Glioma Brain Tumor. Even three and a half years after his diagnosis, I still don’t really know much about Gliomas, so I have decided to research this topic.

A tumor in the brain is dangerous if it starts to compress parts of the brain causing neurological symptoms. This action can destroy the brain tissue it surrounds or it can block fluid in the brain from flowing. Although it is not cancerous it can also compress parts of the spinal cord depending where it is in the brain and can also stop the flow of blood in veins surrounding it.

Glioma is a solid primary tumour that starts in the brain and has a very high mortality rate. Brain tumours are most common in adults but can also affect children. There are two types of tumours one type is called the low-grade tumour and this is the slow growing tumours that are referred to as non-malignant. High-grade tumours are fast growing and are referred to as malignant tumours. However even though there are different grades they both have the potential to cause harm. The high grade which are cancerous are the most difficult to treat this is because of highly vascularized nature of the tumour. Treating high-grade gliomas requires specific alterations within the cells. Patients who suffer from a brain tumour will have many symptoms.

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

Brain tumors grow from abnormal cells which can be cancerous or noncancerous. Symptoms of brain tumors are headaches, muscular weakness like difficulty walking, whole body balance disorder, gastrointestinal (nausea or vomiting), sensory disorder like pins and needles, cognitive or mental confusion, speech (impaired voice), and very common blurred vision. There are various treatments for brain tumors. One includes chemotherapy which kills cells growing or multiplying too quickly. Surgery like craniotomy, this is brain surgery where a piece of bone is removed from the skull. And radiation therapy that uses X-rays to kill abnormal cells. Cancer cells can break off from the tumor into the bloodstream where they can go anywhere in the body. Noncancerous and cancerous brain tumors occur in about 12 in 100,000 people a year.

Brain Cancer is one of the primary cancers in children and young adults. Brain cancer is a malignant tumor in the brain that can grow and spread aggressively, overpowering healthy cells by taking their space, blood, and nutrients. Some tumors can metastasize to other parts of the body causing further destruction of healthy cells. The most common primary brain tumors are gliomas, meningiomas, pituitary adenomas, vestibular schwannomas, and primitive neuroectodermal tumors (medulloblastomas), named according to the part of the brain they originate in. The cause of most brain cancers are unknown, but Genetic factors, various environmental toxins, radiation to the head, HIV infection, and cigarette smoking have all been linked to cancers of the brain.

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,

A brain tumor is an irregular growth of tissue in the brain or central spine that can disturb proper brain function. There are two types of brain tumors that can either be considered malignant (cancerous), or benign (noncancerous). Doctors denote a tumor according to where in the body the tumor originated. Tumors that are designated as benign are noncancerous because they are the least aggressive type. They begin from cells surrounding the brain, however, they are not comprised of cancerous cells. A malignant tumor is the most life-threatening tumor, as the cancer cells do not have clear borders; thus, they grow rapidly without a clear sign of where it is in proximity to the brain tissue. Furthermore, the other well-known brain tumors are primary

Neuroblastoma can either be benign, which means the tumor is not cancerous and it just needs to be removed, or it can malignant, which means the tumor is

Brain cancer is a devastating, hard to treat condition in which a tumor forms within the cranium of a human. It develops when the normal cells experience a mutation that causes the cells to grow and divide at a rapid pace, while killing healthy cells. In result, this rapid growth later develops into a dangerous tumor. The brain is an extremely sensitive section of the human body, brain cancer cannot be treated easily with surgery. Nevertheless, there are many types of brain cancer, and Glioblastoma is a specific, rare brain cancer condition.

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,
