Radiotherapy: The Cause Of Brain Tumors

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.

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.

Brain cancer develops from cells within the brain. The brain controls the vital functions of the body, including, speech, movement, thoughts, feelings, memory, sight, hearing, and more. Brain cancer affects people in many different ways. Brain cancer is diagnosed at the local stage in 76.6% of people. The 5-year survival for localized brain and other nervous system cancer is 36.3%. Brain cancer will cause anything from headaches to balance and walking problems, changes in your vision, muscle twitches, memory problems, and nausea and vomiting.

Malignant gliomas are the most common type of primary brain tumors. As already shown in the Central Brain Tumor Registry of the United States (CBTRUS) report from 1998 – 2002, gliomas account for approximately 80 % of all malignant brain tumors and at least 30 % of all brain and CNS neoplasms (Ostrom et al., 2014). A number of putative risk factors that have been associated with brain tumors have been discussed. However, there is no clear cause for brain and CNS tumors. Less that 1 % are linked to lifestyle or environmental factors (Parkin, Boyd, & Walker, 2011). The only exposure that has been shown to affect glioma risk is ionizing radiation and has been classified as a cause by the International Agency for Research on Cancer (IARC) (Cogliano

Brain cancer is a disease of the brain in which cancer cells appear in the brain tissue. When these cancer cells form a tumor it can interfere with important functions of the brain such as memory and control of muscles. According to the National Cancer Institute and the American Cancer Society, brain cancer occurs uncommonly and will develop in approximately 22,850 people per year, with and estimate of 15,320 deaths.

A brain tumor can ruin other parts in your body. It can spread throughout your entire body. Cancer that spread throughout your body is call secondary brain tumor or brain metastases. Cancer cell break apart from the main tumor and spread to other places of your body. Then it grows again on another part of the body. Then the cycle of a tumor starts again.

The brain houses the control system of the whole body. The brain controls the personality. The brain controls the body’s movements. The brain controls what makes people themselves, but what if the brain got infected? The personality changes. They have trouble walking. They start to have difficulty with speech. The person now can not stay themselves. It’s scary and horrifying, but it consist of brain cancer. Brain tumors begin when abnormal cells multiply without stopping and, they begin to form a mass, then it begins to become a tumor; there are many types, and symptoms, treatment, and all kinds of doctors to treat it.

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

Some of the issues and complications using chemotherapy and radiotherapy are that, some chemotherapeutic agents are excluded by the blood-brain barrier (BBB) and that is why novel methods of intracranial drug delivery systems are being developed to deliver higher concentration of chemotherapeutic agents to the tumor cells while avoiding the adverse systemic effects of these medications. Although chemotherapy targets dividing tumor cells, there are normal dividing cells in the body, which are consequently targeted and may lead to side effects. In men, chemotherapy can cause mutations in the sperm, which can be harmful to the growth and development of a fetus; therefore, it is crucial not to father a child while taking the

However, some tumor can't be surgically removed owing to their position in the brain. In those circumstances, chemotherapy and radiation therapy are both choices for killing and shrinking the tumor. Since treatment for cancer also can damage healthy tissue, it is significant to discuss possible side and long term effects of whatsoever treatment is being used with your doctor. There are three standard kinds of treatment for malignant tumors: surgery, chemotherapy, and radiation therapy. New treatments are continually being researched and used in clinical trials throughout the globe. For some patients, clinical trials are the finest choice of treatment. Rehabilitation could encompass working with diverse therapies such

Glioblastoma can be either primary or secondary depending on the key genetic mutations in the tumour, which also predict the survival of the suffering patients. Primary glioblastoma contributes to more than 90% of the glioblastoma cases, and arise

Primary glioblastoma multiforme accounts for the majority of cases (60%) in adults older than 50 years. These tumors manifest de novo (i.e. without clinical or histopathologic evidence of a preexisting, less-malignant precursor lesion), presenting after a short clinical history, usually less than 3 months. Secondary glioblastoma multiformes (40%) typically develop in younger patients ( cells of the arachnoid villi in the meninges. These tumors usually are benign in nature; however, a small percentage of these tumors are cancerous.

Cancer is the uncontrolled and invasive growth of cells; mostly all cancers cells lead to the formation of a mass of cells known as a tumor. Brain cancer is where this uncontrolled growth of cells, malignant cells, emerges in the tissues of the brain. Brain cancer is one of the many cancers where tumors arise. There are two different kinds of these cancerous brain tumors: primary and secondary brain tumors. Primary brain tumors develop directly in the brain, while secondary, or metastatic, brain tumors spread to the brain from other areas of the body. Around 20-40% of all other cancers, like breast and lung cancer, later develop brain metastases. Brain cancer is sadly one of the most prevalent cancers found in kids and adolescents, ages

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,

Primary brain tumours are those that originate in the brain or the tissues that surround it, for example, cranial nerves, brain-covering membranes, pineal gland or pituitary gland.
