Green tea has been called "natural defense" against cancer. Population studies linking green tea consumption with a lower risk of cancer which has led some to advocate the incorporation of green tea in the diet. After all, what's the downside? However, population studies can not prove cause and effect. It is "impossible to determine ... whether green tea actually prevents cancer in people," until you put it to the test.
Natural defense capacity or green tea often disebbut adala one natural remedy against cancer. yan research linking green tea consumption with a lower risk of cancer that causes some people to consume green tea for cancer as well antidote to the diet. But you know, green tea in the study population may yet prove cause and effect as well as proving really can prevent cancer in people.
Prostate cancer is initially preceded by precancerous condition dkenal as intraepithelial neoplasia. This past year, approximately 30% of the lesions turn cancerous condition.
it happens because no treatment is given by a patient to be diagnosed. It is utilized sebaian people to leave and try green tea.
Thus, 60 men with precancerous prostate intraepithelial neoplasia randomly into a group of green tea or a placebo. It's hard to make a convincing placebo tea; so, they use the pill-coarse green tea equivalent to about six cups of green tea a day-compared to a sugar pill.
Six months into the study, they took a biopsy of all people, and in the placebo group, 6 of 30 developed cancer at the midpoint, and then three of the remaining 24 by the end of the year. So, 9 out of 30 in the placebo group suffered from cancer, or 30% -which is what usually happens when you do not do anything; about 30% continues to develop cancer in the first year.
But, in the green tea group, did not develop cancer in the first six months, and only one at the end of the year. Thus, only one out of 30; almost ten times less than the placebo group-the first demonstration that green tea compounds can be "very effective for treating pre-malignant lesions before [prostate cancer] develops." And, even a year later, after they stopped green tea, nearly 90% of the original green tea group remained free of cancer, while more than half of the placebo group had cancer. This suggests that the benefits of green tea may be "durable" -Overall reduction of almost 80% in prostate cancer. That is quite impressive.
What if you already have prostate cancer? A green tea extract supplement belonged given to 26 men with confirmed prostate cancer for an average of about one month before their prostate removed, and there is a significant reduction in the number of cancer biomarkers such as PSA levels, showed tumor shrinkage. But, there was no control group and the study was funded by a supplement company itself. But when an independent group of researchers tried to replicate the results in, double-blind, placebo-controlled, they failed to find a statistically significant increase. So, green tea may be effective only in the precancerous state, but not strong enough to affect prostate cancer that clear?
Certainly not seem to help for advanced metastatic cancer in two studies that try. And recently, no doubt has been cast on the results of precancerous. When researchers tried to mimic it, green tea extract group only seems to curb the growth of prostate cancer by about half, which, because of the small number of people in the study, may very well have happened just by chance. So, where does that leave us?
Unfortunately, the green tea extract pill is not without risk there are around a dozen case reports of liver damage associated with their use. And, until there is more evidence of the strong benefits I'll stick with just drinking tea.
Okay, green or black? A recent study randomly about a hundred men with prostate cancer to consume six cups of green or black tea a day were found a significant decrease in PSA levels and NF-kappa beta in the green tea group, but not black tea or a control group. NF-kappa beta considered prognostic marker for prostate cancer progression; and so, green tea seems to work better than black.
