Can Green Tea Affect Prostate Cancer?

Also in studies on the diet and cancer show that green tea when tested with mice with an aggressive form of cancer can decrease the spread or metastasis to the liver, bones and other body parts.

Some newer research reveals that green tea might help prevent the spread of prostate cancer. Specifically the phytochemicals found in green tea, called polyphenols attack the growth factors and protiens interupting the growth processes of tumors, resulting in preventing them from spreading to other organs of the body.

Now because earlier studies showed that the same natural plant substances may also help to prevent the start of prostate cancer itself, researchers indicated that more studies need to be done on green teas affect on fighting this common type of cancer. The best way to reduce your risk of prostate cancer still lies in eating a mostly vegetarian diet.
Phytochemicals in green tea seem to increase the number of enzymes that help convert carcinogens in the body to a dormant, or harmless forms. Numerous questions still remain about the amount and or frequency of green tea necessary to affect the formation of prostate cancer itself.

Black tea has also shown similar benefits and effects to green tea, although they appear to have somewhat lower levels of the beneficial substances than green tea has. Whatever the benefits of green tea, it would be a big mistake to rely on the teas alone for this prevention.
Other tests and studies suggest a variety of nutritional influences on prostate cancer risk. Vitamin E use may also offer some protection.
