The exact cause of most cases of<unk>  is not known. Most children with leukemia do not have any known risk factors. One hypothesis is that<unk>  acute lymphoblastic leukemia (ALL) is caused by a two-step process, starting with a prenatal genetic mutation and then exposure to infections While this theory is possible, there is not enough evidence in patients currently to either support or refute the relationship between infection and developing ALL There is evidence linking maternal alcohol consumption to AML development in children. Indoor insecticide exposure has also been linked to the development of<unk> s. High levels of coffee consumption during pregnancy (2-3 cups/day or greater) have been linked to<unk>  as well. It has also been suggested that allergies are linked to the development of<unk>  but this is not supported by current evidence.
