Drinking Green Tea Before Prostatectomy Helps in Slowing Down the Progression of Prostate Cancer
A new research has suggested that if men take about 6 cups of green tea consistently for some days before they are due for the surgical removal of their prostate gland, then it really can help in reducing the inflammation or tumor.
The new research was presented at the prevention conference of the American Association for Cancer Research.
Although the research is still preliminary but it still works pretty much to support other related studies that have linked the role of green tea extract on the reduction of cancer build up on the prostate gland.
Here is an extract that provides more details about this research:
Six cups of green tea a day may slow the progression of prostate cancer, a new study suggests.
The finding stems from research that showed prostate patients scheduled for a type of surgery known as a prostatectomy, where the prostate is removed, reduced their levels of some disease-associated inflammation by drinking lots of brewed green tea in the weeks preceding the operation. And that reduction in inflammation may inhibit tumor growth, the researchers suggested.
Their results were to be presented Thursday at the American Association for Cancer Research’s annual prevention conference in Anaheim, Calif.
The notion that the polyphenol compounds found in green tea might have a protective effect against prostate cancer has yet to be confirmed outside a laboratory setting. However, this latest report builds on previous Italian research that suggested that consuming green tea extract may help lower the risk that a precancerous condition will develop into full-blown prostate cancer.
And related research that was also presented at the cancer research conference suggested that the flavonoids found in fruits and vegetables may be associated with a lower risk of developing aggressive prostate cancer.
However, at least one urologist, Dr. Mark Soloway, chairman emeritus of urology at the University of Miami Miller School of Medicine, pointed to the new study’s limitations, and said it was too soon to say that green tea had any impact on prostate cancer.
Scientific findings presented at meetings should be viewed as preliminary until published in a peer-reviewed journal.
In this latest green tea study, men who drank the beverage for three to eight weeks prior to surgery experienced a noticeable drop in both serum prostate-specific antigen (PSA) concentrations and PSA protein expression by the time they went under the knife. The fall-off in such telltale signs of disease was accompanied by reductions in both disease-linked inflammation and oxidative DNA damage, the study authors said.
“To see this effect, you would need to drink a lot of green tea,” stressed study author Susanne Henning, a registered dietician and adjunct professor with the University of California, Los Angeles David Geffen School of Medicine. “Two cups a day is not going to help. In fact, we had our men drink six cups spread out all throughout the day, which I think was beneficial because green tea polyphenols are excreted very rapidly, so if you drink it that way you keep your levels up. And that seems to be the important factor in keeping the protection going.”
To explore the anti-cancer potential of green tea, the authors focused on 67 prostate cancer patients, all of whom were weeks away from surgery. About half the men were randomly assigned to a six-cup-a-day regimen of green tea leading up to surgery, while the others consumed water instead.
The result: Blood and urine samples analyzed alongside tissue samples taken during surgery revealed that the green tea group fared significantly better on key signs of inflammation, PSA levels and expression and DNA damage.
However, no notable difference was found between the two groups in terms of tumor cell growth.
Henning stressed the need for more research on the potential green-tea/prostate cancer connection, and her team is currently planning new animal investigations involving combinations of green tea and other natural foods.
While this research showed an association between green tea and prostate cancer, it did not prove a cause-and-effect link.
“Actually, several food agents have been under investigation for their protective impact,” she noted. “Lycopene and omega-3 fatty acids, for example. So, I would say that if you have cancer and you want to make a decision about all of this, then think of incorporating all of those as a part of a lifestyle change. I know that if I was diagnosed with prostate cancer, I would try to change my lifestyle. And that would mean, in addition to eating lots of fruits and vegetables and trying to lose weight and exercising, that I would definitely drink green tea.”
The University of Miami’s Soloway said that while drinking green tea probably does not have a downside, this “limited study” does not confirm its impact as a prostate cancer intervention.
“[There's] not much solid data to prove it,” he said. “This is a small study, and it would take a longer study with hundreds of patients to ‘prove’ its benefit.” Click here for more details on this research.
The above extract has highlighted the role that green tea extracts could play in helping to treat prostate cancer. The study is still preliminary but so far the research has really proven effective.
Prostate cancer affects many men than other types of cancer and helping to get rid of it early helps to save the life of the person.
The Green Tea study above is a limited one, but can really help to provide basis for further research.
In addition, men can really take advantage of this study and consider drinking green tea so as to improve their prostate health.
