Men looking for another healthy reason to drink green tea may not look further. A new study suggests that an antioxidant found in green tea can prevent prostate cancer growth, interrupting the spread of cancer cells and hunting the tumor. A previous study in mice suggested that polyphenols found in green tea can stop the development of prostate cancer and growth, and researchers say that this study helps to explain the mechanism behind this potential benefit of health. The researchers say the polyphenols of green tea seem to combat prostate cancer, aiming at the mechanisms that trigger the spread of cancer cells, as well as stopping the growth of neighbors of neighboring vessels that feed the tumor.
The results of the study appear in the December 1 issue of cancer research. The study is the latest of many who suggest that drinking green tea provides a variety of health benefits ranging from reducing the risk of heart disease to combat cancer.

In the study, the researchers analyzed the role of antioxidants found in green tea in the development of prostate cancer and progression in mice. An earlier study showed that giving the mice the human equivalent of six cups of green tea per day stopped the growth of prostate cancer.
The researchers examined how the green tea antioxidant affected a protein known as insulin-like growth factor - 1 (IGF-1). Increased IGF-1 levels were found in men with prostate cancer.
They found that the rats that received the green tea antioxidant had lower IGF-1 levels in their blood.

Researchers say the green tea antioxidant seemed to stop cell growth, decreasing the production of various proteins that promote cellular survival. In addition, it has reduced the production of proteins that are known to be associated with the dissemination of cancer cells.
Finally, the study also suggests that antioxidant in green tea seemed to pass through the tumor cells of prostate cancer, inhibiting the formation of blood vessels, thus suppressing the flow of nutrients into the cancer cells.
