Decades later, Vietnam vets may be silently fighting cancer-causing parasite
A small pilot study hints that a startling number of Vietnam veterans may be infected with a liver parasite that can induce a rare type of cancer, the Associated Press reports.
The study, conducted by the Northport VA Medical Center in New York, involved blood samples from 50 Vietnam veterans. Testing performed at Seoul National University in South Korea found that more than 20 percent of those samples were positive or borderline positive for antibodies against the parasite, a liver fluke.
The results are preliminary and require follow-up research. It’s also unclear how the 50 blood samples were chosen. That said, the results hint that many veterans may have the cancer-inducing infection and not yet know. The study follows a report last year by the AP, which raised questions about the rate of that otherwise rare type of cancer in veterans.

About 700 veterans with cholangiocarcinoma were seen at VA facilities in the past 15 years. But less than half filed for service-related benefits. It’s likely that many did not know that their cancer may be linked to parasite exposure during their time in Vietnam. Moreover, the VA rejected 80 percent of the requests.
