Can Drinking Green Tea Battle Cancer?
A number of research results have demonstrated that green tea has certain properties that are beneficial for preventing cancer. Places like Japan where tea is frequently used, show lower instances. Nevertheless, researchers have yet to claim with absolute certainty that tea can prevent cancer. Research hints however, that the antioxidant polyphenols contained in tea may be a significant tool in the fight. This article will discuss the link between tea and certain specific types of cancer.
There have not been many studies looking at the connection between the consumption of green tea and bladder cancer. One research project has determined that women who consumed tea decreased their chances of suffering from this disease. Subsequently, it was shown that men drinking tea benefited from a higher rate of survival over a period of five years.
Research carried out on animals has shown that polyphenols found in tea prevent the development of cells that cause breast cancer. Studies have demonstrated that in women drinking the greatest amounts of tea, breast cancer spread at the slowest rate. This was particularly prominent with early detection in women who had not yet reached menopause. Recurrences of wer also fewer in those who drank several cups of green tea on a daily basis. Similarly, it was found that women suffering from ovarian cancer that consumed tea daily lived longer than women who did not.
As regards colorectal cancer, the results have not been definitive. More studies are needed in order to determine whether tea can have beneficial effects.
The situation is similar with esophageal cancer. While research on animals has demonstrated positive results, with humans the results were less definitive. Some studies have even shown that green tea can lead to higher risk. This was especially true when the tea was drunk hot. Scientists must carry out more studies before suggesting green tea as a way of inhibiting this disease.
Conflicting results were also obtained for lung, prostate and stomach cancer. More research is needed to examine the link between tea consumption and these diseases.
Research reports studying the effects of green tea on skin and pancreatic cancer is cautiously more optimistic. Epigallocatechin gallate (EGCG), which is the principal polyphenol found in green tea, has been proven to have attributes that are capable of inhibiting the appearance and development of tumors on the skin. One study has shown that tea may be beneficial for preventing pancreatic cancer, but others have shown that there is no link between the popular herb and this particular disease.
Clearly, more work has to be done here. At the present time, there seems to be as much anecdotal evidence as hard facts to support or dismiss green tea as a possible tool in the battle against this disease. The benefits are very dependent on the particular strain in question. The good news is, that research is ongoing, and will continue until a cure or prevention is discovered.
