The Benefits of Green Tea for Oral Cancer

Oral cancer frequently arises from precancerous lesions in the mouth. 59 patients with precancerous oral lesions were randomized into a tea group. Within six months, lesions in 11 of the 29 in the tea group shrunk compared to only three out of 30 in the placebo group. The protective effects of green tea applied topically was also seen in precancerous cervical lesions.
