The main health risk most commonly associated with military service in Vietnam is exposure to Agent Orange , a herbicide used during the war that contained the toxic contaminant dioxin (TCDD).

Key associated health risk

  • Agent Orange exposure has been linked to several serious long-term conditions, including certain cancers (such as non-Hodgkin’s lymphoma, prostate cancer, and soft-tissue sarcoma) and other chronic diseases like type 2 diabetes and ischemic heart disease.
  • Because of this evidence, the U.S. Department of Veterans Affairs presumes that veterans who served in Vietnam and later develop specific Agent Orange–associated diseases were exposed to this chemical during their service.

Why Agent Orange stands out

  • Many possible health issues can follow combat, but Agent Orange is uniquely recognized in laws and veterans’ benefit policies as a specific service-connected risk for those who served in Vietnam.
  • Question formats that ask “Which of the following health risks is associated with military service in Vietnam?” almost always intend “Agent Orange exposure” as the correct choice when it appears among the options.
