Green Tea And Cervical Cancer
Green tea and cervical cancer? Long lauded for its health benefits, green tea is being studied to see if it can have a positive effect on cervical cancer.
The Arizona Cancer Center in Tuscon, Arizona, is testing the effect that green tea extract will have on a group of viruses that can cause cervical cancer, in the hope of finding a non-surgical way of preventing the disease.
Dr Thomas, research specialist at the center, is hopeful of finding that green tea extract (EGCG) will provide an alternative to current treatments for HPV infection that are very invasive; involving freezing or removing a portion of a woman's cervix.
The $1 million study will eventually involve 150 women in Arizona and surrounding states, who are currently infected with human papillomavirus.
This is the most commonly sexually transmitted infection in the United States, with an estimated 20 million people carrying the virus.
The participants will take either a placebo or a capsule containing 800mg.(equivalent to about 8 cups of green tea) of EGCG for 4 months.
The hope is that the EGCG will target and destroy the HPV before precancerous lesions or other changes to the cervix appear.
There is a vaccine for HPV, but it can only be given to patients who haven't had the infection before, so alternative solutions must be found for women who are carriers already.
Women need more options when faced with the threat of this cancer and it is hoped that green tea may provide a natural way of destroying the precancerous conditions.
Side effects of very high doses of green tea extract have already been found to be tolerated well by patients in other studies. This study is funded by the National Cancer Institute's Division of Cancer Prevention.
