The Department of Veterans Affairs, the federal agency that provides healthcare and benefits to former service members, would be required to study how common bile duct cancer (a rare cancer sometimes linked to a parasite called liver fluke found in Southeast Asia) is among veterans who served in Vietnam, comparing their cancer rates to the general U.S. population. The VA would also have to keep track of this cancer using its existing cancer database and regularly send updates and findings to Congress. In practice, this means Vietnam veterans wouldn't see any new benefits or coverage right away, but the government would be gathering data that could help determine whether their service put them at higher risk for this cancer, which could inform future decisions about care or compensation.
