Green Tea May Fight Lung Cancer

Green Tea Extract Tweaks Lung Cancer Cells WebMD 3/12/07 "So far, the scientists have only tested green tea extract against human lung cancer cells in test tubes, not people...Lu and colleagues exposed a sample of human lung cancer cells to a decaffeinated green tea extract. The lung cancer cells marinated in the green tea extract for up to three days. The green tea extract remodeled a certain protein in the lung cancer cells. As a result, the lung cancer cells became more likely to stick together and less likely to move...Antioxidants in green tea may have tweaked the cancer cell protein, but it's not clear whether one antioxidant deserves all the credit or whether several antioxidants worked together...The study doesn’t prove that drinking green tea curbs lung cancer in people. However, it may be possible to make new lung cancer drugs based on green tea extract, Lu's team suggests. Such drugs would target the lung cancer protein remodeled by the green tea extract in the lab tests."
