The many types of brain tumors are divided into two categories: primary tumors and metastatic tumors. Primary tumors start within your brain whereas metastatic tumors start somewhere else and travel to your brain. Metastatic tumors are always cancerous while a primary tumor can be noncancerous.
Symptoms vary based on the complexity of the brain, the type of tumor and its location. A tumor could cause physical problems including headaches, nausea and seizures. It can also cause behavioral changes such as confusion and impulsiveness.
Tumors are treated in different ways including medication, radiation or surgical removal.
