"Wild animals normally are killed by cancer only in rare cases. But scientists are finding that some deadly cancers in animals--including Quebec's belugas, California sea lions and North Sea flounder--seem to be triggered or accelerated by environmental contaminants. The cancers highlight the dangers that industrial activities pose - not just to animals, but to people in the same areas, exposed to the same chemicals. But lack of research and environmental obstacles mean most cancers in wildlife remain undetected."
