Researchers Hunt For Elusive Environmental Causes of Leukemia
(This is the second of two articles on research into the causes of childhood leukemia.)In the midst of growing public concern about environmental exposures that may increase risks for childhood leukemia and other cancers, a number of far-reaching epidemiological studies are under way, and researchers say results in the next few years should provide important clues if not definitive answers.
Environmental causes of childhood cancer have long been suspected by many scientists, and the public seems even more convinced that these risks exist. But the causes have been difficult to pin down, partly because cancer in children is rare and partly because potential risk factors are so many and various.
Last September, the U.S. Environmental Protection Agency, spurred by concerns that childhood cancer rates may be increasing, held the first-ever national conference to explore possible links between childhood cancer and environmental causes and to recommend a federal strategy to
