Astrocytoma

fully understand what it is all about. Let me start by saying that GBM is the highest grade of glioma brain tumors, so it only makes sense for me to tell where GBM and glioma tumors come from. A glioma is a type of brain tumor that grows from glial cells, cells that support nerve cells with energy and nutrients and help maintain the blood-brain barrier. There are various types of glial cells, each with a different function. Astrocytes transport nutrients and hold neurons in place, oligodendrocytes provide insulation, myelin, to neurons, microglias digest dead neurons and pathogens, and ependymal cells line the ventricles and secrete cerebrospinal fluid. Glioma is an umbrella term used to describe the different types of glial tumors, astrocytoma, oligodendroglioma, and glioblastoma. Gliomas vary in their aggressiveness, or malignancy. Some are slow-growing and are likely curable, while others are fast-growing, invasive,…

Astrocytoma is one of the most common brain cancers that rise from astrocytes. Astrocytoma is also referred to as gliomas because they come from glial tissues. Astrocytoma is divided into subdivisions: grade I, a noninfiltrating tumor; grade II, it’s a low-grade Astrocytoma and is an infiltrating tumor; grade III, also referred to as Anaplastic (malignant) Astrocytoma because the tumor grows quickly; and grade IBM and it is the most aggressive type of tumor. This topic is important and…

Any tumor that arises from the supportive tissue or glial cell, of the brain is called a “glioma” [8]. Astrocytoma is the one type of glyoma. It is named after astrocytes. Astrocytes are star-shaped cells from which they grow.According to the degree of abnormality Astrocytomas are graded in to I to IV classes [8] .These classes are Pilocytic Astrocytomas (PA) , Diffuse Astrocytoma, Anaplastic Astrocytomas(AA) and Glioblastoma Multiformeor( GBM) . Pilocytic Astrocytomas are generally slow…

Cells Interacting: Astrocytoma in its cancerous form is a situation in which a malignant tumor starts in Astrocyte cells, which have the purpose of protecting nerve cells. As the tumor grows invasively into these cells, it presses on the nerve cells and other parts of the brain. Cancerous astrocytoma will grow very quickly, spreading into other sections of brain tissue. As it does this, it will start to push on the brain itself and stop it from functioning properly. …. Function: The…

The management of patients with spinal cord astrocytoma remains controversial, and there are currently no universally accepted treatment guidelines. As described in previous studies, the most significant predictor of survival in patients with SCA is the pathological grade of this disorder [4, 5, 12]. In the present study, similarly, patients who had low-grade SCA had a significantly better prognosis than those with high-grade SCA. Additionally, the role of surgical resection remains unclear,…

masterminded into these general classes: A. Gliomas These tumors happen in the glial cells, which bolster and ensure basic ranges of the brain. Gliomas[6] are the most widely recognized sort of brain tumor in grown-ups, in charge of around 42% of all grown-up brain tumors. Gliomas are further described by the sorts of cells they influence: B. Astrocytoma These are Star-formed cells that protected neurons. Tumors of these cells can spread from the fundamental site to distinctive regions of the…

Assisted Suicide: The suicide of a patient suffering from an incurable disease, effected by the raking of lethal drugs provided by a doctor for this purpose. Assisted suicide is currently illegal in 45 states, last Monday, Governor Jerry Brown passed a bill to legalize it in California, making California one of only five states to allow assisted suicide. Brittany Maynard was diagnosed with terminal brain cancer at the young age of 29 on January 1st 2014. It was a grade 2 astrocytoma; it then…

Not soon after her marriage, Brittany started to experience unbearable headaches. Her headaches were discovered to be the results of a brain tumor. Test were performed and result revealed that the brain tumor was a cancerous form Grade II Astrocytoma. Grade II Astrocytoma is a low-grade astrocytomas and are the slowest growing tumors. Brittany was given anywhere from 3-5 years with a maximum of 10 years to live with this initial diagnoses. Seventy days post-op, Brittany received detrimental…

Association, 2014). MRIs with and without contrast are used to identify glioblastomas, which are easily spotted by a dark center of necrotic tissue surrounded by a white ring of inflammation (Figure 1) (Omuro and DeAngelis, 2013). However, due to the similarity of glioblastomas and metastasized gliomas for MRI imaging, most will require biopsies to identify the tumor type. Glioblastomas are classified into primary and secondary. Primary Glioblastomas (approximately 90% to 95% of all…

Euthanasia is the practice of painless and intentional killing to relieve a patient of pain and suffering from a terminal illness. Euthanasia is also known as “mercy killing” and it differs from assisted (physician) suicide. It’s been a heated debate for centuries whether or not euthanization should be legalized, especially in the US. Euthanasia is illegal in all states, but physician-assisted suicide is available in certain state but, California has the Natural Death Act which allows a…
