Large clinical studies focusing on the association between fish oil, EPA, DHA and cancer have largely been inconclusive. The team tested whether mice lacking ALOX15 responded differently to fish oil supplements compared to control mice. "Not all fish oil supplements are the same," said Imad Shureiqi, professor of internal medicine at the University of Michigan and a member of Rogel Cancer Center. Shureiqi recommends that people talk to their physicians before they take fish oil supplements.
