Polyphenols in tea from green leaves are called catechins or known as epigallocatechin 3 gallate (EGCG). This EGCG can cause cancer cells to die, as well as the effect on normal cells. This effect is important to note because cancer cells differ from normal cells and normal body cells do not need to be killed when these cells continue to grow and spread in the body.
Some laboratory studies show that green tea can help prevent certain cancer growth. These include cancers of the skin, lungs, breast, bladder, liver, prostate, large intestine and esophagus. This study shows that compounds in tea can help block blood vessels from supplying blood to cancer cells.
