What is the cause of childhood cancer?

Cancer in children tends to be different from cancer in adults; childhood cancer is more associated with problems during development in the womb. [9] Adult cancer is more associated with damage to the genetic material that accumulates over time.

Established risk factors for developing childhood cancer include:
  • Family history of cancer
  • Presence of genetic defects in the child
  • Use of certain chemotherapy drugs [15]
  • Exposure to ionizing radiation (X-rays, radiation from atomic bomb) [11-14]
