The Department of Veterans Affairs wants Vietnam Veterans to be aware of a rare cancer linked to two different risk factors they may have been exposed to in Southeast Asia. Cholangiocarcinoma (bile duct cancer) is a cancer of the biliary duct system, which includes the gallbladder, bile ducts, and certain cells inside the liver. The risk factors are exposure to liver flukes and dioxin, which is in Agent Orange. The rare cancer becomes more common as people grow older. The VA recently created a page to let Veterans and others who served in areas where these liver flukes are prevalent be aware of the symptoms of Cholangiocarcinoma. Many advocates are pushing the VA not to deny service connection to Cholangiocarcinoma if the Veteran didn’t show symptoms in the service or within a year after discharge. Experts say this cancer is symptomatic and, in most cases, takes 30 to 40 years to develop.
