Brain tumor may be Metastatic brain tumor and primary brain tumor. Malignant brain tumor multiplies and spread faster. Benign brain tumor, though dangerous, tend to be confined to their location.

Also called secondary brain cancer, it occurs when cancer invades the brain from other parts of the body, mainly from the breasts, kidneys, lungs, colon and skin. They appear mostly in the cerebral cortex, the brain stem or the cerebellum. Sometimes, doctors cannot trace the origin of the metastasis.
