Tumors can be primary or secondary.

Primary tumors of the CNS are growths that begin in your brain or spinal cord. They can be either malignant or benign.
Metastatic tumors, or secondary tumors, of the CNS are caused by cancer cells that break away from a primary tumor somewhere else in your body and spread to the CNS. They are more common than primary tumors of the CNS and occur more often in adults than in children.
