It was found that green tea extract could delay the development of oral cancer

Although studies have shown that green tea has a certain anti-cancer effect, this conclusion still needs to be confirmed by human experiments In a new study, US researchers found that green tea extract can at least delay oral cancer In a report published in the November issue of cancer prevention research, researchers from the University of Texas in the United States said that in order to study the anti-cancer effect of green tea, they conducted a comparative study on the clinical treatment of 41 patients with oral leukoplakia Oral leukoplakia is a common precancerous disease Generally speaking, 50% of leukoplakia will turn into oral cancer The researchers gave one group of patients a drug made from green tea extract and another a placebo Some time later, the researchers found that patients taking green tea extract showed a trend of improvement in the pathogenesis of oral tissue and some biomarkers Biomarkers are important tools for monitoring and tracking cancer development In more than two years of follow-up, a total of 15 people suffered from oral cancer Although in general, there was no significant difference between the number of patients who took green tea extract and those who did not, the development of the former was generally slower than that of the latter, and the final time of oral cancer was also later However, the researchers pointed out that although the results are encouraging, they do not advocate to rely on green tea to prevent cancer completely at present, and its anti-cancer effect still needs further study Previous studies have found that a substance called green tea polyphenols in green tea can reduce Bcl-xL protein, which can prevent cancer cells from apoptosis.
