But the cancer cells do not die, they just keep on growing and mass of the tumor grows. At one point the mass becomes so much that they spread in the body through blood.

For grade I and II the cells look almost normal under the microscope and they grow slowly as compared to the normal cells. But grade I is benign and grade II is malignant, but if not treated on time the benign tumor may become malignant tumor. For grade II and IV the cells looks quite abnormal than normal cells and they grow very rapidly. The types of brain tumor that affect adults are Astrocytoma, Meningioma and Oligodendroglioma and the types of brain tumor that affects children are Medulloblastoma, Astrocytoma, Ependymoma and
