Green tea may slow prostate cancer

ACTIVE compounds in green tea may slow down the progression of prostate cancer, researchers reported yesterday.

Capsules made using green tea extracts called polyphenols lowered levels of proteins that tumors use to grow, the researchers found.

Made by Polyphenon Pharma, the capsules called Polyphenon E contain epigallocatechin gallate or EGCG, a green tea extract that has antioxidant properties.

Jim Cardelli of Louisiana State University Health Sciences Center in Shreveport and colleagues tested 26 prostate cancer patients.

Each took four Polyphenon E capsules a day -- equivalent to 12 cups of green tea -- for about a month before they had their prostates removed.

Blood tests showed levels of three proteins associated with the growth and spread of prostate cancer fell.

Bigger studies will be needed to confirm the results.
