What are brain and spinal cord cancers?
... The brain and spinal cord make up the central nervous system (CNS). The CNS receives messages from cells called nerves, which are spread throughout the body in the peripheral nervous system. The brain interprets information and relays messages through the nerves to muscles and organs. The brain cont ...
