More green tea anti-cancer secrets revealed
The researchers found that women receiving green tea extract had significantly lower levels of cancer tumour growth factors two months later.
The small study was led by Katherine D. Crew, an assistant professor of medicine and epidemiology at Columbia University Medical Center in New York. The team looked at 40 women with a type of breast cancer that does not respond to hormone therapy. The polyphenols in green tea appear to be the powerful anti-cancer agents as they inhibit two proteins that promote tumor cell growth and migration — namely, the vascular endothelial growth factor (VEGF) and the hepatocyte growth factor (HGF).
Study presented on October 18, 2012 to the 11th Annual International Conference on Frontiers in Cancer Prevention Research in Anaheim, California as hosted by the American Association for Cancer Research.
Another study by Susanne Henning, an adjunct professor at the David Geffen School of Medicine at the University of California Los Angeles, as presented to the same conference involved 67 men who started drinking green tea daily as they were preparing to undergo the removal of an enlarged or cancerous prostate.
The researchers found that the men who drank the green tea had significantly lower levels of prostate-specific antigen (PSA). Elevated PSA is associated with prostate tumor growth.
This type of ‘green tea lowers prostate cancer risk’ research has been done before. A published 2009 study of 26 men with prostate cancer by James Cardelli of the Louisiana State University Health Sciences Center in Shreveport, La. Cardelli, and colleagues, found a similar positive effect with green tea reducing prostate cancer growth.
In Japan, where green tea consumption is high, prostate and breast cancer rates are only around 20% of the rates in most of the Western world.
