As of March 2015, there is not enough evidence to show a link between Agent Orange and melanoma, a type of skin cancer, based on analysis by the Institute of Medicine (IOM). Research by IOM and organizations such as the United States Centers for Disease Control and Prevention has linkedexposure with Agent Orange to several other cancers, such as non-Hodgkin's lymphoma, chronic lymphocytic leukemia and soft tissue sarcoma.
Agent Orange is a herbicide that kills plants by causing leaves to fall off. It was used by the U.S. military during the Vietnam War to clear vegetation and destroy crops around U.S. bases. As a result, some of the three million American troops that served during the war were exposed to Agent Orange. Since then, researchers have been studying whether the exposure increases the risk of cancer.
