There is no clear evidence that green tea can help to cure cancer. Green tea is made from the dried leaves of the plant Camellia sinensis, and contains chemicals known as polyphenols. These are antioxidants that may help to prevent DNA damage caused by free radicals, and this is why some people think that tea can help to prevent or cure cancer.

Some laboratory studies have shown that tea polyphenols can stop cancer cells from growing; however, studies in humans show variable results.

In , the internationally respected Cochrane Collaboration reviewed all the clinical studies on the effect of green tea on cancer prevention or death from cancer. The results were conflicting — some showed that green tea could help prevent cancer, some showed that it had no effect and some showed that it increased the risk of some cancers.

Subsequent reviews and analyses found similar results. This means that, overall, the studies on green tea and cancer are inconclusive for all types of cancer, and more large-scale clinical trials need to be done before we can be sure whether green tea helps to prevent or cure cancer.

Green tea is made from the leaves of Camellia sinensis, a plant full of polyphenols, the active ingredient found in many green teas. Catechins, a subgroup of polyphenols, are powerful antioxidants that are thought to be responsible for most of the health benefits attributed to green tea.

According to the National Cancer Institute NCI , EGCG can protect cells from DNA damage, activate detoxification enzymes that inhibit tumor growth, and promote cancer cell destruction.

Researchers have found the effects of tea on the skin include decreasing the risk of cell carcinoma and cutaneous malignant melanoma a more severe type of skin cancer. One of the most exciting new developments in the study of what catechins are and can do is a new study from the University of Salford in the UK which analyzed the effects of matcha on human breast cancer cells.

Matcha cancer-fighting properties are also linked to the prevention of other types of cancer.

Drinking green tea in moderate amounts is not associated with any significant harmful effects. However, evaluations by the International Agency for Research on Cancer determined that drinking any very hot beverage above 65°C is probably a cause of oesophageal cancer.

Close Print. Some research even indicated that green tea consumption may actually increase the risk of bladder cancer. In another research review published in the British Journal of Nutrition , investigators analyzed 18 previously published studies.

Green tea consumption was significantly inversely associated with a five percent lower risk of cardiovascular disease and all-cause mortality , but not with mortality from cancer.

Published in the Annals of Epidemiology , a prospective study following 90, people in Japan found that green tea was inversely associated with mortality from heart disease and mortality from cerebrovascular disease and respiratory disease in men.

No association was found between green tea and total cancer mortality. As a whole, the evidence that green tea consumption can reduce the risk of cancer is conflicting. Large-scale clinical trials—the kind of research you want to see to put full stock in a treatment—need to be conducted before drinking green tea can be considered an effective strategy to reduce cancer risk.

Although it can be discouraging to hear that there is no clear answer yet, researchers do state that green tea appears to be safe for most people when consumed in moderate amounts. Drinking green tea may offer other health benefits, including reduced risk of stroke and periodontal disease. If you're considering drinking it regularly, be sure to consult your healthcare provider first to discuss whether it's appropriate for you.

People with certain conditions and those taking medications such as bortezomib may have to avoid it. To reduce your overall cancer risk, be sure to get routine cancer screening tests, follow a balanced, healthful diet that includes plenty of fruits, vegetables, and other foods from plant sources, maintain a healthy weight, exercise regularly, and avoid smoking.

Green tea usually contains the highest amount of EGCG, but all teas contain valuable antioxidants. Herbal teas are often called tea.

But they are not made from the tea plant and are not caffeinated. The proper name for these drinks is Tisane; they include options like chamomile, peppermint and Rooibos.

A sub group of these polyphenols is called catechins. The catechin in green tea is called epigallocatechingallate EGCG. Researchers think that EGCG has an anti-tumour anti-cancer effect. These lab results are encouraging. But we need evidence from human studies to prove them.

The evidence at the moment from human studies is mixed. In , a Cochrane review looked into green tea being used for the prevention of cancer.

Overall there were 1,, participants across all of the studies that were looked into. Overall, the evidence showed that the effects of having green tea to lower cancer risk were inconsistent. They did find a slight improvement in quality of life for people who took green tea.

Researchers published an overview of studies a meta analysis in It suggested that green tea could reduce the risk of developing mouth cancers. In researchers did another review and meta analysis of several studies. It showed that green tea might help to prevent breast cancer.

And that it might especially help to prevent breast cancer from coming back. But the studies in the review were small. The researchers said that we need more scientific studies looking at greater numbers of people.

The research looking at whether it prevents prostate cancer generally and in pre cancerous prostate cells is mixed with some showing it might and others not showing any evidence.

But a review study in suggests that the substances in green tea in laboratory research and early clinical trials suggests it may be of benefit. They suggest we need more research. Researchers did a study in on 39 patients. It was on people at risk of colon and rectal cancer.

They found that green tea did not reduce the amount of aberrant crypt foci ACF. ACF are groups of abnormal tube-like glands in the lining of the colon and rectum.

They are early changes in the colon and rectum and can lead to cancer. We need more evidence from randomised controlled clinical trials. This can help us to know whether green tea has a role in preventing cancer. Request an appointment at MD Anderson online or by calling My Chart.
