Vietnam

us government scientists recently changed their stand on the link established in an earlier report between cancer and Agent Orange, used to defoliate jungles during the Vietnam.

The revised Institute of Medicine report says there is not enough evidence to prove whether children of Vietnam war veterans have a higher risk of acute myelogenous leukemia (aml), a deadly blood cancer.

In April 2001, the institute had reported that there was a probable link between aml in children and their parents' exposure in Vietnam to Agent Orange, a herbicide that contains carcinogenic dioxins.
