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

  • Your age. Most people diagnosed with chronic lymphocytic leukemia are older than 60.
  • Your sex. Men are more likely than are women to develop chronic lymphocytic leukemia.
  • Your race. Whites are more likely to develop chronic lymphocytic leukemia than are people of other races.
  • Family history of blood and bone marrow cancers. A family history of chronic lymphocytic leukemia or other blood and bone marrow cancers may increase your risk.
  • Exposure to chemicals. Certain herbicides and insecticides, including Agent Orange used during the Vietnam War, have been linked to an increased risk of chronic lymphocytic leukemia.
