A malignant brain tumor is a cancer of the brain. It's relatively common - slightly more so in men than in women - and may occur at any age. In adults, it most often strikes between ages 40 and 60. In children, the incidence of malignant brain tumors is generally highest before age 1 and then again between ages 2 and 12. Malignant brain tumors CogniQ are classified by the type of cancer cell. In adults, the most common tumors are gliomas and meningiomas. Usually, these tumors are located above the covering of the cerebellum - the area in the back of the brain that coordinates voluntary muscle movements.
