How do primary brain tumors happen?

ANSWER

Primary brain tumors emerge from the various cells that make up the brain and central nervous system and are named for the kind of cell in which they first form. The most common types of adult brain tumors are gliomas as in astrocytic tumors. These tumors form from astrocytes and other types of glial cells, which are cells that help keep nerves healthy.
