Green Tea May Block Prostate Cancer

Green tea contains chemicals called polyphenols that appear to slow the progression of prostate cancer, at least in mice, according to a report in the journal Cancer Research. Dr. Hasan Mukhtar, at the University of Wisconsin in Madison, and colleagues previously showed that feeding mice green tea polyphenols blocked the development and progression of prostate cancer. In the current study, the researchers clarified the chemical basis for this observation. They found that polyphenols inhibited a chemical pathway that plays a key role in the development of prostate cancer.
