Green tea beneficial in fight against cancer


Scientists in Sweden say they have discovered why green tea, a popular drink in China and Japan, has a protective effect against some forms of cancer.

A report by researchers in Stockholm, published in the scientific journal 'Nature', says that a substance in green tea slows down or stops the growth of new blood vessels.

A BBC science correspondent says that as cancer tumours are dependent on a constantly growing network of blood vessels to supply them with food and oxygen, they will shrink and may even disappear, if the network stops growing.

He says its now clear why moderate consumption of green tea can be beneficial. He says that unlike black tea, green tea is not squashed to rupture its cells and cause fermentation reactions as it dries.
