Green Tea Slows Prostate Cancer Progression.

New research shows that green tea polyphenols may help slow or prevent some types of cancer. A double-blind, placebo-controlled study found that premalignant prostate lesions were three times less likely to progress to malignant tumors in men who took a 600mg green tea catechins supplement daily for a year (9% vs. 30% in the control group).
