DescriptionAn in-depth report on the causes, diagnosis, treatment, and prevention of leukemia.Alternative NamesAcute lymphoblastic (or lymphocytic) leukemia Risk Factors:AgeALL in Children. ALL is the most common type of cancer diagnosed in children. ALL accounts for about 75% of cases of childhood leukemia. Each year, about 3,600 American children and adolescents are diagnosed with ALL. ALL can strike children of all ages, but is most likely to occur when children are 2 - 4 years of age. It is slightly more common in boys than in girls. ALL in Adults. ALL is the least common type of leukemia among adults. About 1 in 3 cases of ALL occur in adults. Race and EthnicityCaucasian and Hispanic children have a higher risk for ALL than African-American children. Hereditary DisordersALL does not appear to run in families. But certain inherited genetic disorders may increase risk. For example, children with Down syndrome have a 20-times greater risk of developing ALL than the general population. Other rare genetic disorders associated with increased risk include Klinefelter syndrome, Bloom syndrome, Fanconi anemia, ataxia-telangiectasia, neurofibromatosis, Shwachman syndrome, IgA deficiency, and congenital X-linked agammaglobulinemia. Radiation and Chemical ExposurePrevious cancer treatment with high doses of radiation or chemotherapy can increase the risk for developing ALL. Prenatal exposure to x-rays may also increase risk in children. Lower levels of radiation (living near power lines, video screen emissions, small appliances, cell phones) are unlikely to pose any cancer risk. Resources
