The human brain consists of cerebellum, cortex portion, brain stemsection, cranium region with different minor cells. Each region in humanbrain performs different operations for activation of the cells in human brain.The muscle movement functions are monitored and maintained by thecerebellum portion of the human brain. It is main responsible region for themovement of the human body into various looking directions. The cortexportion is the largest region in human brain which is responsible for thememory and awareness activity functions. The cranium is otherwise called asthe skull which is over coated on the human brain tissues. The internal regionsor cells in the human brain are secured by this layer of tissues in the craniumregion. The abrupt spikes in each cells in the brain region forms or createsthe cancer. Cancer starts in cells, the structure obstructs that make tissues.Tissues make up the organs of the body. Ordinarily, cells develop and gap toframe new cells as the body needs them. At the point when cells develop old, they pass on, and new cells have their spot. Sometimes this orderly proceduremay become wrong, and then the generation of new cells stop and old cellsbecome stable and did not expire on time. Brain tumor as shown is a very injurious disease for human life. The World Health Organization (WHO) and American BrainTumor Association (ABTA) have initiated grading mechanism for tumorstages into grade I to grade IV to classify benign and malignant tumor types.Grade I and II are called low-grade brain tumors or benign tumor.
