Primary brain tumors make first in the brain itself or in tissues close to it, Such as in the brain - covering membranes ( meninges ), cranial nerves, pituitary gland or pineal gland.Primary brain tumors begin when normal cells develop changes ( mutations ) in their DNA. A cell 's DNA has in it the teachings that say to a cell what to do. The mutations say to the cells to grow and divide rapidly and to go on living when healthy cells would die. The outcome is a mass of abnormal cells, which forms a tumor.In adults, primary brain tumors are much less common than are secondary brain tumors, in which cancer begins elsewhere and covers all over to the brain.
