Association Found Between
Magnetic Fields And Leukemia
TORONTO - Researchers in Toronto have found an association between childhood leukemia and high magnetic-field levels from sources such as power lines.
The study compared 201 children with leukemia with 406 children without cancer. The children exposed most to magnetic fields in residences were two to four times more likely to have leukemia. Children under age six were especially at risk.
But lead researcher Dr. Lois Green said the five-year study doesn't mean magnetic fields cause cancer.
Leukemia attacks blood cells and is the most common childhood cancer.
The study is among many attempting to clarify the relationship between electromagnetic fields and cancer risk.
The team's findings were released this week in the International Journal of Cancer and the journal Cancer Causes and Control.
