People with cancer should consult with neart doctor before adding tea to their regimen. Breast cancer. Studies in animals and test tubes suggest that polyphenols in green tea inhibit the growth of breast cancer cells. In one study of women with various stages of breast cancer, researchers found that women who drank the most green tea had the least spread of cancer.
It was especially true in premenopausal women in the early stages of breast cancer. They also found that women with early stages of the disease who drank at least 5 cups of tea daily before being diagnosed with cancer were less likely to experience a recurrence after they finished treatment.
However, women with late stages of breast cancer had little or no improvement from drinking green tea. There is no clear evidence one way or the other about green tea and breast cancer prevention. In one very large study, researchers found that drinking tea, green or any other type, was not associated with a reduced risk of breast cancer.
Ovarian cancer. In a study done with ovarian cancer patients in China, researchers found that women who drank at least one cup of green tea per day lived longer with the disease than those who did not drink green tea.
In fact, those who drank the most tea, lived the longest. But other studies found no beneficial effects. Colorectal cancer. Studies on the effects of green tea on colon or rectal cancer have showed conflicting results. Some studies show decreased risk in those who drink the tea, while others show increased risk.
In one study, women who drank 5 or more cups of green tea per day had a lower risk of colorectal cancer compared to non-tea-drinkers. However, there was no protective effect for men.
Other studies show that drinking tea regularly may reduce the risk of colorectal cancer in women. More research is needed before researchers can recommend green tea for the prevention of colorectal cancer. Esophageal cancer. Studies in laboratory animals have found that green tea polyphenols inhibit the growth of esophageal cancer cells.
However, studies in people have produced conflicting findings. For example, one large-scale population-based study found that green tea offered protection against the development of esophageal cancer, particularly among women. Another population-based study found just the opposite, green tea consumption was associated with an increased risk of esophageal cancer.
In fact, the stronger and hotter the tea, the greater the risk. Given these conflicting results, more research is needed before scientists can recommend green tea for the prevention of esophageal cancer. Lung cancer. While green tea polyphenols have been shown to inhibit the growth of human lung cancer cells in test tubes, few clinical studies have looked at the link between drinking green tea and lung cancer in people, and the studies that have been done show conflicting results.
One population-based study found that Okinawan tea, similar to green tea but partially fermented, was associated with lower lung cancer risk, particularly among women. But a second study found that green tea and black tea increased the risk of lung cancer.
More studies are needed before researchers can draw any conclusions about green tea and lung cancer. Green tea should not be used by patients on bortezomib therapy. Pancreatic cancer. In one large-scale clinical study researchers compared green tea drinkers with nondrinkers and found that those who drank the most tea were less likely to develop pancreatic cancer.
This was particularly true for women, those who drank the most green tea were half as likely to develop pancreatic cancer as those who drank less tea. However, it is not clear from this population-based study whether green tea is solely responsible for lowering pancreatic cancer risk.
More studies are needed before researchers can recommend green tea for the prevention of pancreatic cancer. Prostate cancer. Laboratory studies have found that green tea extracts prevent the growth of prostate cancer cells in test tubes.
A large clinical study in Southeast China found that the risk of prostate cancer went down with increasing frequency, duration, and quantity of green tea consumption. However, both green and black tea extracts also stimulated genes that cause cells to be less sensitive to chemotherapy drugs.
People who are undergoing chemotherapy should ask their doctors before drinking green or black tea, or taking tea supplements. Skin cancer. The main polyphenol in green tea is epigallocatechin gallate EGCG.
Scientific studies suggest that EGCG and green tea polyphenols have anti-inflammatory and anticancer properties that may help prevent the development and growth of skin tumors. Stomach cancer. Laboratory studies have found that green tea polyphenols inhibit the growth of stomach cancer cells in test tubes, however, studies in people have been less conclusive.
In two studies that compared green tea drinkers with nondrinkers, researchers found that people who drank tea were about half as likely to develop stomach cancer and stomach inflammation as those who did not drink green tea.
However, a clinical study with more than 26, men and women in Japan found no association between green tea and stomach cancer risk. Some studies even suggest that green tea may increase the risk of stomach cancer. Green tea may help reduce inflammation associated with Crohn disease and ulcerative colitis, the two types of IBD.
If green tea proves to help prevent colon cancer, it would also help those with IBD because they are at higher risk for colon cancer. Green tea has been used traditionally to control blood sugar levels. Animal studies suggest that green tea may help prevent the development of type 1 diabetes and slow the progression once it has developed.
In people with type 1 diabetes, their bodies make little or no insulin, which helps convert glucose or sugar into energy. Green tea may help regulate glucose in the body.
Research also suggests that regular consumption of green tea may help manage type 2 diabetes. Population-based studies have shown that men who drink more than 10 cups of green tea per day are less likely to develop liver problems. Green tea also seems to protect the liver from the damaging effects of toxic substances such as alcohol.
Animal studies have shown that green tea helps protect against liver tumors in mice. Results from several animal and human studies suggest that plant chemicals in green tea called catechins, may help treat viral hepatitis, an inflammation of the liver. In these studies, catechin was used by itself in very high amounts.
It is not clear whether green tea, which has a lower concentration of catechins, would have the same benefits. It is important to note that 10 cups of green tea a day could cause problems due to high levels of caffeine. Ask your doctor about the best way to include green tea in your treatment.
Clinical studies suggest that green tea extract may boost metabolism and help burn fat. One study found that the combination of green tea and caffeine improved weight loss and maintenance in people who were overweight and moderately obese.
However, other studies show no benefit. Preliminary studies suggest that drinking green tea can help prevent dental cavities.
