Green Tea and Cancer Prevention

Cancer is caused by uncontrolled growth of cells. It is one of the world’s leading causes of death.  It is known that oxidative damage contributes to the development of cancer and that antioxidants may have a protective effect.

Green tea is an excellent source of powerful antioxidants, so it makes sense that it could reduce your risk of cancer, which it appears to do:

  • Breast cancer: A meta-analysis of observational studies found that women who drank the most green tea had a 20-30% lower risk of developing breast cancer, the most common cancer in women.
  • Prostate cancer: One study found that men drinking green tea had a 48% lower risk of developing prostate cancer, which is the most common cancer in men.
  • Colorectal cancer: An analysis of 29 studies showed that those drinking green tea were up to 42% less likely to develop colorectal cancer.

Many observational studies have shown that green tea drinkers are less likely to develop several types of cancer. However, more high-quality research is needed to confirm these effects.

It is important to keep in mind that it may be a bad idea to put milk in your tea, because some studies suggest it reduces the antioxidant value.
