Green tea has been praised for its possible health benefits, but now a new study finds it could be detrimental for some cancer patients.The concern is green tea may counteract the beneficial effects of a widely used anti-cancer agent called Velcade.

The drug normally fights cancer by inducing tumor cell death. However, scientists discovered green tea polyphenols and other components actually prevented Velcade from killing tumor cells.

Researchers say the findings of this study are specific for patients taking Velcade as opposed to any other common cancer drug.
