Brain tumors are a result of uncontrolled growth of cells in the brain. This growth can be cancerous or noncancerous and cause damage to brain tissue which leads to loss of certain functions. Brain cancer is the 10th leading cause of death. There are 4 grades of brain tumors classified by the World Health Organization based on specific components of each type of tumor. Several factors seem to affect whether an individual is diagnosed with brain tumors: age, exposure to radiation, ethnicity and race, family history, weak immune system, and gender. There are various symptoms of brain tumors that are general as well as specific to the location of the tumor. Many types of treatments are available for brain tumors today such as surgery, radiation therapy, chemotherapy, and targeted therapy. This article works to provide an overview of brain tumors discussing the types, risk factors, symptoms, diagnosis, treatments, and preventions.
