Green tea always make some surprising for people health.
Now, extending benefits from green tea just found. It may cut the risk for Lung cancer. Moreover to the person with have smoking habits.

The researcher says, people who drank at least 1 cup of green tea everyday have low risk compared with people who did not drink green tea that have 5.16-fold increased risk of lung cancer.

I-Hsin Lin, MS, a student at CHung Shan Medical University in Taiwan said, “Our results suggest that both smokers and nonsmokers could benefit by drinking green tea. Green tea contains strong antioxidants called tea polyphenols, which have inhibitory effects of tumorgenesism tumor proliferation, and tumor growth.”

And for the smokers, she said, “Drinking green tea may provide a chance to lower the lung cancer risk in smokers, but it cannot reverse the toxic effects or carcinogenesis caused by smoking. We don’t want smokers to use this as an excuse to keep smoking and thinking that they have a lower risk by drinking a cup of green tea every day.”

In their study that have correlation to insulin-like grow factor level of IGF1, IGF3, and IGFBP3 showed 66% reducing in lung cancer risk was observed in green-tea drinkers with nonsusceptible IGF1 in some genotypes such as (CA)19/(CA)19 and (CA)19/X.

They found that smoking, consuming less than 1 cup of green tea per day, and exposure to cooking fumes for more than 3 hours per week were associated with an elevated risk for lung cancer. But after adjustment for the effects of exposure to cooking fumes, a significantly higher risk was observed in people who never drank green tea, particularly to smokers.

Ms. Lin said, “Our study suggest that in the case of lung cancer, smoking-induced carcinogenesis could be modulated by green-tea consumption and the growth-factor environment.”
