Cambodians are at a high risk of liver cancer, Dr. Taing Tek Hong, a Cambodian physician living in Florida, said Thursday.

The leading causes of the disease are Hepatitis B, alcohol abuse, the overuse of painkillers like Tylenol and smoking, he said. Cambodians are exposed to all these risks, he said.

Iron, copper and parasites in the liver can also lead to the disease, as can food toxins, Taing Tek Hong said, as a guest on "Hello VOA."

Ascites, a disease the causes a distended belly, comes from a liver infection or cirrhosis, he said. Cirrhosis comes from liver shrinkage due to prolonged alcohol abuse, he added.
