Drinking green tea may reduce the risk of lung cancer in both smokers and nonsmokers, new research suggests. The study was done in Taiwan. It included 170 people with lung cancer and 340 healthy people. They were asked questions about their diet, tea drinking and smoking. They also were given gene tests. People with some variations in their genes are more likely to develop lung cancer than others. In the study, lung cancer risk was 13 times lower for smokers who drank at least one cup of green tea daily than for smokers who drank none. Nonsmokers’ risk of lung cancer was five times lower among tea drinkers. Tea drinkers with “low-risk” genes were even less likely to have lung cancer. Researchers said the best way to prevent lung cancer is to avoid smoking. The study was presented at a conference on lung cancer. HealthDay News wrote about it January 12.

Green tea extract may help to delay oral cancer in people at risk, new research suggests. Researchers gave green tea extract to 41 people who had pre-cancerous cells in their mouths. The dose was equal to 8 to 10 cups of green tea daily. Another group received placebos. The study lasted 28 months. In that time, people who took green tea extract were just as likely as the other group to develop oral cancer. But in one group who took green tea extract, the cancer took longer to develop. This was the group of people who had mild to moderate abnormal cell growth at the start of the study. Study results were released online by the journal Cancer Prevention Research.
