<prompt> Which of the following does not predispose to leukemiaAlcoholGenetic disorderSmokingChemical exposure  <response>: Leukemia risk factors1 GeneralGender: Men are more likely to develop CML, CLL and AML than women.Age: The risk of most leukemias, with the exception of ALL, typically increases with age.2 GeneticsFamily history: First-degree relatives of CLL patients, or having an identical twin who has or had AML or ALL, increases the risk for developing the disease.Genetic diseases: AML has been associated with Down syndrome, Klinefelter syndrome, Patau syndrome, Fanconi anemia, Bloom syndrome, Ataxia telangiectasia, and Kostmann syndrome, may play a role in the development of leukemia.3 SmokingSmoking cigarettes does increase the risk of developing AML4 Exposures Radiation : Exposure to high-energy radiation e.g., atomic bomb explosions and intense exposure to low- energy radiation from electromagnetic fields e.g., power lines. Chemical exposure: Long-term exposure to chemicals like benzene ethylene oxide is considered to be a risk for leukemia.Drugs - alkylating agents topoisomerase II inhibitors increase the risk of AML.5 Previous Cancer TreatmentCertain types of chemotherapy and radiation therapy for other cancers are considered leukemia risk factors.
