WEDNESDAY, Aug. 6 (HealthDay News) -- Vietnam veterans exposed to the defoliant Agent Orange have a significantly greater risk of prostate cancer, especially the most aggressive form of the disease, a new study contends.
The findings are the first to connect the now-banned herbicide with this form of cancer, the researchers said.
"Veterans that were exposed to Agent Orange during the Vietnam War have a twofold higher risk of prostate cancer," said study lead author Dr. Karim Chamie, a resident physician in urology at the University of California, Davis, Department of Urology and the VA Northern California Health Care System. "The cancer they get tends to be more aggressive, a higher grade, and is more likely to spread or have spread at the time that they present to their urologist."
