Brain Cancer
Also called: Glioma, Meningioma
There are two main types of brain cancer. Primary brain cancer starts in the brain. Metastatic brain cancer starts somewhere else in the body and moves to the brain. Brain tumors can be benign, with no cancer cells, or malignant, with cancer cells that grow quickly.
Brain tumors can cause many symptoms. Some of the most common are
Headaches, usually worse in the morning
Nausea and vomiting
Changes in your ability to talk, hear or see
Problems with balance or walking
Problems with thinking or memory
Muscle jerking or twitching
Numbness or tingling in arms or legs
No one knows the exact causes of brain tumors. Doctors can seldom explain why one person develops a brain tumor and another does not.
