People should sign this because Vietnam Veterans are dying from this disease. It is a fact that one of the causes of the cancer is ingestion of the Liver Fluke. It is a fact that the Liver Flukes are endemic in Vietnam and it's surrounding areas. It is a fact that cases have been approved by the Veteran's Administration agreeing that veterans have gotten this cancer due to their service in Vietnam. It is a fact this cancer is rare in the United States. It is not fair that many Vietnam Veterans are once again being overlooked, and they are not given the recognition they deserve for their service to their country.
