Green tea can help reduce the risk of prostate cancer

This article is for all the men and for ladies who have men in their life, aka pretty much anyone. The article states that 80% of men will be diagnosed with prostate cancer by the time they are 60 years old. Prostate cancer is the most common cancer for men. This is a really short article and does not state the percentage of drinking a couple cups of green tea can help reduce prostate cancer, just that it can. I do not doubt it can help with prostate cancer, but was hoping on a percentage of or another nominal amount especially since it states 80 % and 2 cups of green tea a day.
