Cancer types A to Z


Most cancers are named after the body part or cell where it started, for example, cancer that begins in the stomach is called stomach cancer.

Cancers are also grouped into larger categories:

  • Carcinomas begin in the skin or tissues that line or cover internal organs.
  • Central nervous system cancers begin in the brain or spinal cord.
  • Leukemia begins in tissues that make blood cells, like bone marrow.
  • Lymphomas and myelomas begin in the immune system.
  • Sarcomas begin in bone, fat, muscle, blood vessels, or cartilage.
