Vietnam Veterans Liver Fluke Cancer Study Act

This bill requires the Department of Veterans Affairs (VA) to conduct an epidemiological study and report on the prevalence of cholangiocarcinoma (bile duct cancer) in veterans who served in the Vietnam theater of operations during the Vietnam era. The study must identify the rate of incidence of cholangiocarcinoma in such veterans and in U.S. residents.

The bill also requires the VA to track and report on the prevalence of cholangiocarcinoma using the Veterans Affairs Central Cancer Registry. Additionally, the VA must periodically submit follow-up reports to Congress regarding the epidemiological study and information collected from the cancer registry regarding the prevalence of bile duct cancer.
