Green Tea Catechins as Novel Antitumor and Antiangiogenic Compounds
 (PubMed, Current Medicinal Chemistry Anti-cancer Agents, 7/2/02)

Researchers in Montreal, Canada, report that tea is a popular beverage that has the potential to play a part in preventing cancer through dietary means. Studies have shown that green tea polyphenols (GTPs) consist of catechins, which are known for their antioxidant effect. These green tea catechins may also affect biological processes that play key roles in the development of cancer, including angiogenesis (growth of new blood vessels), extracellular matrix degradation, regulation of cell death and multi-drug resistance.
