July 29 (UPI) -- Liver cancer: In most cases, it doesn't have to happen, a new global study finds.

Research suggests that 60% of cases of this often deadly disease are preventable by avoiding or treating big risk factors.

Those risk factors include viral hepatitis infection, alcohol misuse or a dangerous, obesity-linked buildup of fat in the liver.

The finding highlights "a huge opportunity for countries to target these risk factors, prevent cases of liver cancer and save lives," said study first author Dr. Stephen Chan of the Chinese University of Hong Kong.
