Dr. Nagle says that although previous animal studies have shown tea can inhibit the growth of ovarian cancer cells, the results of human studies are contradictory. "However, our results support the idea that antioxidants in tea may be useful against cancer."

"Green tea is considered the healthiest form of tea. Although our results do not show a stronger effect of drinking green tea, a combination of all the evidence around the world shows that consumption of one or more cups of green tea per day may reduce the risk of cancer ovarian 40%. But this must be confirmed by additional research. "
