Brain Cancer - Research Paper Example The growth of cancer cells in the brain tissue is termed as brain cancer. A tumor or mass of cancer tissue is formed by the cancer cells. These tumors affect the functions of the brain, such as memory, muscle control and memory. Tumors are classified as malignant, when they are comprised of cancer cells. On the other hand, tumors consisting of non – cancerous cells are termed as benign (Davis & Stoppler, 2013). Furthermore, cancer cells resulting from brain tissue are termed primary brain tumors; whereas the cancer cells that spread to the brain from other sites in the body are termed as metastatic brain tumors. It has been projected, by the available statistics that brain cancer could develop in approximately 22,000 individuals per year. Moreover, 13,000 deaths could occur due to cancer (Davis & Stoppler, 2013). Symptoms Individuals with glial origin tumors depict general, non – focal signs and symptoms, or focal manifestations pertaining to the specific region of the brain where the tumor is located. The most frequently observed symptoms among such individuals include headache, nausea, vomiting, generalized seizures and alterations in the level of consciousness. Headache tends to accompany several instances of brain tumors; nevertheless, only a few individuals with headache have a brain tumor (Pan & Prados, 2003). Headache tends to be the sole symptom in a fifth of the patients with brain tumors. Such headaches vary between moderate to severe, tend to be intermittent, and pronounced to a greater degree in the early morning, or increase with coughing and other actions that enhance the intracranial pressure. Headaches that are associated with increased intracranial pressure tend to be generalized, non – focal and non – lateralizing to the location of the tumor. Furthermore, tumors can be localized by headaches that are not associated with enhanced intracranial pressure (Pan & Prados, 2003). In 15% of the cases, the initial manifestat ions of brain tumors are seizures. In addition, 30% of the individuals with brain tumors could develop seizures in the long run. Usually, seizures transpire along with the slower developing and superficial tumors that involve the sensorimotor cortex (Pan & Prados, 2003). Some of the rapidly developing brain tumors may not present seizures as a distinguishing feature, but may do so eventually. With respect to adults, the onset of a new seizure necessitates neuroimaging, so as to eliminate the presence of a brain tumor as the underlying cause. Brain tumors have been seen to prevail to the extent of 10% among patients suffering with generalized seizures (Pan & Prados, 2003). With regard to children, seizures had been observed to result from intracranial tumors in less than a hundredth of the instances. This could be indicative of the fact that the majority of the central nervous system lesions in children transpire infratentorially. All the same, if a child exhibits seizures that tend to be difficult to control, then magnetic resonance imaging techniques have to be used, in order to evaluate the condition. In general, the brain tumors that cause seizures in children tend to be slow growing neoplasms (Pan & Prados, 2003). Increase in intracranial pressure can cause vomiting in a patient with glial tumors. On rare occasions, such vomiting can be due to invasion by the tumor of the vagal nucleus in the posterior fossa. Sometimes, a rapid
