People infected with hepatitis B are about twice as likely to develop non-Hodgkin's lymphoma, according to a study done in part by the U.S. National Cancer Institute.

Hepatitis B was already known to cause liver cancer. The new study, which is published in the Lancet Oncology, confirms it as a cause of lymphoma as well.

Researchers in the U.S. and South Korea analyzed 600,000 patients over a 14-year span for the study.

An estimated 350,000 people are infected with hepatitis B worldwide.
