Primary malignant brain tumors account for two percent of all cancers in U.S. adults. They are classified based on their type of cells and appearance. Symptoms may include persistent headaches, seizures, nausea, vomiting, neurocognitive symptoms, and personality changes. These can vary depending on the type, size, and location of the tumor.
Brain tumors can be identified with imaging, usually beginning with magnetic resonance (MRI), and a comprehensive neurosurgical evaluation. Tissue samples may be needed to confirm any diagnosis. Primary brain tumors rarely metastasize (spread) outside the central nervous system.
Primary brain tumors may be treated with surgery, radiation, chemotherapy, or a combination of all three. In many instances, the physicians within the Peak Brain & Pituitary Tumor Center at Houston Methodist Hospital will offer novel investigational treatments with a high likelihood of success through multi-center trials.
