Study From Portugal: Green Tea 'Promising Agent' in Kidney Cancer

Posted by

Green Tea Just released by the World Tea News (Monday, April 12, 2010):

"Researchers at the University of Porto in Portugal have concluded a study indicating that green tea may be an effective anticancer agent for renal cell carcinoma (or RCC), the most common type of kidney cancer in adults and one of the most deadly.

The team noted RCC's resistance to chemotherapy and radiotherapy, the resulting urgency to explore the potential of other therapies and the potential for managing other types of cancer that green tea and tea polyphenols have demonstrated in other studies.

With this in mind, the researchers set out to analyze the antiproliferative effect of an antioxidant-rich green tea extract on human renal cancer cell lines. They found that "green tea extract strongly inhibited the growth of both RCC cell lines in a concentration-dependent manner," stated an abstract of the findings. "This is the first report showing that green tea is likely to be an effective anticancer agent for renal cell carcinoma."

A report from the research will appear in the September 2010 issue of the scientific journal Food Chemistry."
