Prostate cancer is cancer that starts in the prostate gland. The prostate is a small, walnut-sized structure that makes up part of a man's reproductive system. It wraps around the urethra, the tube that carries urine out of the body.
GREEN TEA EXCTRACT MAY SLOW PROSTATE CANCER PROGRESS Polyphenon E capsule (green tea extract); Active compounds in green tea may slow down the progression of prostate cancer. Capsules made using green tea extracts called polyphenols lowered levels of proteins that tumors use to grow. 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, aged from 41 to 68. Blood tests showed levels of three proteins associated with the growth and spread of prostate cancer fell. Hepatocyte growth factor or HGF fell 18.9% on average, vascular endothelial growth factor or VEGF fell by 9.9% and prostate specific antigen PSA fell by 10.4%. HGF and VEGF are produced when tumors spread and some patients showed "significant" reduction levels of more than 30 percent. Green tea can keep cancer from growing very fast, but it may not be able to shrink tumors.
