Primary brain tumors are tumors that form from cells within the brain. The tumors are categorized by the type of cell in which it first develops. There are over 120 different types of brain tumors, according to the National Brain Tumor Society. The most common primary brain tumors are called gliomas, which originate in the glial (supportive) tissue. About one third of all primary brain tumors and other nervous system tumors form from glial cells.
