Vietnam Vets may have Cancer-Causing Parasites

Hundreds of Vietnam War veterans may be infected with parasites called liver flukes, which can sometimes lead to cancer, recent research suggests. A recent study from the U.S. Department of Veterans Affairs (VA) found that, out of 50 blood samples submitted from Vietnam veterans, more than 20 percent tested positive for antibodies against liver flukes, according to the Associated Press. The findings could mean that many Vietnam veterans have "silent" infections with the parasite, meaning they don't have any symptoms. However, the results are preliminary, and it's possible that not all of the veterans who tested positive actually have the parasite, the researchers said. Still, the results were "surprising.
Liver flukes are small, flat parasitic worms that can infect the liver, gallbladder and bile ducts. People become infected when they eat raw or undercooked freshwater fish that have the parasites, according to the Centers for Disease Control and Prevention (CDC). Although liver-fluke infections are rare in the United States, it's estimated that 35 million people worldwide are infected with the parasites at any one time, mostly in Asia and Eastern Europe.
There are three main types of liver flukes that cause human infection: Clonorchis sinensis, which is common in rural parts of China and Korea; Opisthorchiasis viverrini, which is found in Thailand, Laos, Vietnam and Cambodia; and Opisthorchis felineus, which is found in a wide geographical area, Including Eastern Europe, Central Asia and Siberia.
Most people who become infected with liver flukes have no symptoms, but some may experience indigestion, abdominal pain, diarrhoea and constipation. However, over long periods, Infection with liver flukes can cause chronic inflammation in the bile ducts, resulting in scarring of the ducts and destruction of nearby liver cells. What's more, the inflammation and scarring of the bile duct can lead to cancer of the bile ducts, which is called cholangiocarcinoma. This type of cancer is rare in Western countries, with only about 7 cases per 1 million people. In the United States, an estimated 8,000 people are diagnosed with bile duct cancer each year.
Symptoms of the cancer can include jaundice (yellowing of the skin), pain in the abdomen, dark urine, liver, itchy skin, vomiting and unexplained weight loss. For people with early-stage bile-duct cancer, about 15 to 30 percent survive at least five years following their diagnosis. However, if the cancer has spread to a distant part of the body, the five-year survival rate is 2 percent.
