The development of ALL includes both genetic and environmental factors with DNA damage in hematopoietic precursor cells being a crucial step.6 Reactive oxygen species (ROS) generated by environmental toxins and chemical carcinogens result in DNA damage.7 Being substrates of carcinogen metabolizing enzymes, the xenobiotics influence their carcinogenic effect depending on a person's ability to activate or inactivate them by conjugation and detoxification of these compounds.8 Variation in genes that encode carcinogen metabolizing enzymes may therefore explain the differences between the individual's capacity to metabolize different chemical carcinogens and have thus received a considerable level of attention with respect to cancer development.
