Brain Tumors: There are 2 categories of brain tumors: primary and secondary. Primary tumors start in brain tissue, while secondary spread to the brain from another site of the body. The most common primary tumors are Gliomas, Medulloblastomas, and Meningiomas. Glioblastoma multiforme is a fast-growing, higher-grade tumor that can arise from a lower-grade glioma and is the most common primary brain tumor in adults. Medulloblastomas are most commonly found in children. Secondary tumors are most commonly spread from the lungs and breast. The major risk factor for secondary tumors is smoking. Symptoms often are developed gradually and may include headache, nausea, vomiting, weakness, change in speech, loss of coordination, visual change most commonly diplopia (double vision), seizures, and memory and personality changes. It’s diagnosed with your history and confirmed with imaging studies (CT, MRI, PET). Treatment depends on the tumor’s size, location, and type, as well as the patient’s age and general health. The main treatments include surgery, radiation therapy, and chemotherapy. A combination of treatments is often used.
