Green tea is a type of a drink that is obtained from steamed and dried leaves of camellia plant.
Research has claimed that green tea can protect certain types of cancers.
However, more research is needed because some human research has produced mixed results.
Examples of these are cancer of the skin, stomach, pancreas, lung, bladder, prostrate and breast. Green tea contains oxidants, which helps prevent cancer.
Green tea is known to contain chemicals like polyphenols, which have antioxidant properties.
Several laboratory tests in animals have claimed that green tea acts against cancer cells.
In addition, elements in tea stops formation of new blood vessel, this is according to test tube tests.
These elements prevent supply of blood to cancer cells.
Some studies have shown that tea drinkers have a lower risk of stomach, breast and colon cancers than those people who do not drink tea. While laboratory studies try to prove that indeed, green tea prevents cancer, there is no scientific research to support such claims.
