Agent Orange tied to aggressive prostate cancer risk

NEW YORK (Reuters Health) - Men who were exposed to Agent Orange chemicals used during the Vietnam War are at higher risk for life-threatening prostate cancer than unexposed veterans, researchers have found.

What's more, those who served where the herbicide was used were diagnosed with cancer about five years earlier than other men, on average, in the new study.
"This is a very, very strong predictor of lethal cancer," said urologist Dr. Mark Garzotto, who worked on the study at the Portland Veterans Affairs Medical Center in Oregon.
"If you're a person who's otherwise healthy and you've been exposed to Agent Orange, that has important implications for whether you should be screened or not screened," he told Reuters Health.
But one researcher not involved in the new study said it's hard to take much away from it, given the imprecise way it measured exposure.
Agent Orange - named after the giant orange drums in which the chemicals were stored - was used by the U.S. military to destroy foliage, mainly in southern Vietnam. The herbicide was often contaminated with a type of dioxin, a potently carcinogenic chemical.
