A recent review of green tea's cancer-preventing properties has yielded mixed results.
For the review, scientists sized up 51 studies (including a total of more than 1.6 million participants) on the link between green tea consumption and a number of cancers (such as those of the breast, lung, digestive tract, and prostate). Their findings revealed that green tea may decrease prostate cancer risk but might have limited benefits for liver cancer. There was also "limited moderate to strong evidence" for green tea's ability to help prevent lung, pancreatic, and colorectal cancer, and conflicting evidence for cancer of the esophagus.
In other studies, green tea has shown potential in protecting against periodontal disease, a condition that may contribute to cardiovascular disease. Green tea also shows promise in the prevention of stroke, the third leading cause of death in the United States.
This study just came out from American Journal of Epidemiology:

Two studies do not show that drinking green tea reduces the risk of breast cancer in women, but one weaker, more limited study suggests that drinking green tea may reduce this risk. Based on these studies, FDA concludes that it is highly unlikely that green tea reduces the risk of breast cancer”; and
“One weak and limited study does not show that drinking green tea reduces the risk of prostate cancer, but another weak and limited study suggests that drinking green tea may reduce this risk. Based on these studies, FDA concludes that it is highly unlikely that green tea reduces the risk of prostate cancer.”
The FDA also concluded that existing evidence does not support qualified health claims for green tea consumption and a reduced risk of any other type of cancer.
Guidance on qualified health claims for conventional foods and dietary supplements was issued by the FDA in July 2003. FDA will continue to evaluate new information that becomes available to determine whether changes in these claims, or in the decision, are necessary
