The rise in mortality doesn’t mean that liver cancer is deadlier than before, according to Dr. Jiaquan Xu, the author of the report; the 10-year survival rate for liver cancer didn’t change much. Rather, the increase in mortality means more people are developing liver cancer.
More than 70% of liver cancers are caused by underlying liver disease, which has risk factors such as obesity, smoking, excess alcohol consumption, and hepatitis B and C infection, said Dr. Farhad Islami
, the scientific director of cancer surveillance research at the American Cancer Society.
“I think the main reason for the increase in liver cancer incidence and death rate in the US is the increase in the prevalence of excess body weight and hepatitis C virus infection in baby boomers,” said Islami, who authored a study on liver cancer
occurrence between 1990 and 2014.
