Cancer in the central nervous system and its surrounding structures

Cancer in the central nervous system and its surrounding structures includes tumors located:
  • intracranially
  • intraspinally

The intracranial tumors include tumors in:

  • the brain (the cerebrum, the brain stem, the cerebellum)
  • the cranial nerves
  • the meninges
  • the pituitary gland

The intraspinal tumors include tumors in:

  • the spinal cord
  • the spinal nerves
  • the spinal cord membrane

The brain and the spinal cord comprise the central nervous system (CNS). The cranial nerves and the spinal nerves belong to the peripheral nervous system.

Incidence

Compared to other cancers, cancer in the central nervous system is relatively rare. Approximately 0.6 % of men and women will be diagnosed with cancer in the central nervous system at some point during their lifetime. This cancer type is most frequently diagnosed among people aged 55-64 and is slightly more common in men than women and among those with certain genetic syndromes. In 2017, it is estimated that there will be 23,800 new cases of cancer in the central nervous system in the United States (16).
