Green tea ineffective against prostate cancer | (UPI) -- Researchers have shown green tea, widely touted for its medicinal properties, is not effective in fighting advanced prostate cancer.

Previous studies had suggested this possibility.

Laboratory research demonstrated an ingredient in green tea kills prostate cancer cells and findings from other studies suggest the tea can reduce the risk of prostate cancer.

However, a Mayo Clinic team in Rochester, Minn., looked at the progress of 42 patients with the disease.

One showed a short-term drop in prostate-specific antigen levels, which indicates treatment progress, but a month later, the level rebounded.

"Green tea failed to show an anticancer effect in the group of patients we studied," researchers said, adding other avenues of treatment should be pursued for the disease responsible for most cancers in men 65 and older.
