Overview of brain cancer, its symptoms, diagnosis and treatment

Abstract

Brain cancer, also known as intracranial neoplasms, represents a group of malignant tumors that originate within the brain or its surrounding tissues. This article provides overview of brain cancer, focusing on its epidemiology, etiology, pathogenesis, clinical presentation, diagnostic approaches, and treatment modalities. The epidemiological data highlights the incidence, prevalence, and risk factors associated with brain cancer, emphasizing the importance of early detection and monitoring. Brain tumors are intracranial tumours that occupy skull space. Brain tumors are a relatively rare but lethal malignancy that presents difficulties in determining risk factors in the community. Because of their protected location in the brain, these tumors are intrinsically difficult to cure, with surgery, radiation, and chemotherapy therapies possibly resulting in long-term morbidity for patients and inadequate tumor cure. Because the space inside the skull is limited, brain tumors are dangerous because their growth raises intracranial pressure and can induce edema, restricted blood flow, and displacement, with subsequent degeneration, of healthy tissue that regulates important processes. In fact, brain tumors are the second largest cause of cancer fatalities in children and young people. Methods of prevention are being developed.
