No clear data green tea helps prevent prostate cancer

Does drinking green tea really help prevent cancer? The answer is still unclear, according to a review of 51 previous studies done over two decades.

The review, published online in The Cochrane Database of Systematic Reviews, found that green tea may offer some help against liver cancer, breast cancer and, in men, prostate cancer, but consumption may actually increase one’s chances of developing urinary bladder cancer. Conflicting evidence was found in the case of gastrointestinal (esophagus, colon or pancreas) cancers, though the authors noted “limited moderate to strong evidence” of green tea protecting against lung, pancreatic and colorectal cancer.”
