Factors that may increase the risk of acute lymphocytic leukemia include:

  • Previous cancer treatment. Children and adults who've had certain types of chemotherapy and radiation therapy for other kinds of cancer may have an increased risk of developing acute lymphocytic leukemia.
  • Exposure to radiation. People exposed to very high levels of radiation, such as survivors of a nuclear reactor accident, have an increased risk of developing acute lymphocytic leukemia.
  • Genetic disorders. Certain genetic disorders, such as Down syndrome, are associated with an increased risk of acute lymphocytic leukemia.
  • Having a brother or sister with ALL. People who have a sibling, including a twin, with acute lymphocytic leukemia have an increased risk of ALL.
