Brain tumor - primary - adults: MedlinePlus Medical Encyclopedia
When a headache gets worse or won't go away, it's natural to wonder whether it could be a symptom of something more serious, like a brain tumor. While headaches can be a symptom of brain tumors, those that are truly tumor-related usually have distinct characteristics or are combined with other symptoms, such as vomiting. In fact, seizures are usually the first sign that a brain tumor might be present. Brain tumors can be benign non-cancerous or malignant cancerous. The symptoms of each are very similar. Symptoms may arise because of impairment of the particular area of the brain where a tumor is located or increased intracranial pressure , which is pressure in and around the brain.
