Green Tea and Prostate Cancer

According to the Prostate Cancer Foundation, prostate cancer is the most common non-skin cancer in America, affecting 1 in 6 men. The foundation estimates that more than 2 million American men currently live with prostate cancer. More than 192,000 men were expected to be diagnosed with this disease in 2009.

Keeping that in mind, the results of a Japanese study should come as welcome news. The study was conducted by researchers in the Epidemiology and Prevention Division of Tokyo’s National Cancer Center. They discovered that men who drink at least five cups of green tea a day can reduce the risk of developing advanced prostate cancer by as much as fifty percent.

Researchers indicated that further studies would be necessary and they also noted that prostate cancer is not as common among Asian men, who tend to drink a great deal more green tea than men in the West. The study was conducted over a period of 14 years and compiled data from 50,000 men aged 40-69.

A study by researchers at the University of Wisconsin found that a component of green tea combined with a low dose of a COX-2 inhibitor might help to slow the spread of human prostate cancer.

According to the National Cancer Institute, part of the National Institutes of Health, catechins might help to inhibit the growth of cancer. Catechins are a type of antioxidant that are abundant in green tea. According to the Japanese study, the catechins in green tea also help to lower levels of testosterone, a male hormone that might be a risk factor for prostate cancer.

The NCI suggests that green tea might have more catechins because it’s subjected to less-intensive processing than other types of tea. Researchers also found that iced tea contains small amounts of catechins, but that green or black tea steeped for five minutes will release more than 80 percent of its catechin content.

Some researchers caution against rushing to judgment when it comes to tea’s alleged cancer-fighting capabilities. Even so, it’s probably safe to conclude that, given its other potential benefits and pleasures, drinking a couple cups of tea a day is hardly a bad idea.
