A new scientific study showed that drinking green tea may help the fight against oral cancer.
59% of the 41 volunteer subjects with "pre-malignant mouth lesions" who drank green tea showed a positive response, while only 18% of those who took placebo showed the same positive effect.
However, we must add that 41 subjects is too little a number to produce really robust statistical results.
Probably that's why the chief scientist of the study, Dr. Vassiliki Papadimitrakopoulo, a professor in the department of thoracic/head and neck medical oncology at the University of Texas M.D. Anderson Cancer Center, said "the findings were encouraging but did not provide definitive proof that green tea can prevent cancer." We agree with him from a statistical point of view.
The subjects were given green tea extracts for 3 months varying between 500 mg and 1,000 mg.
During the 28 months that the study was conducted, 15 people actually did develop oral cancer.
