The study will investigate the effect of green tea on the formation of colon polyps, sometimes seen as
precancerous. German Cancer Aid, a non-profit organisation that receives no public funds, is paying the entire
2.1-million-euro (2.8 million dollars) cost of the project with donations. "In the interests of the people concerned,
we need to exhaust all possibilities for cancer prevention. This includes naturopathic therapies," said German
Cancer Aid spokeswoman Christiana Tschoepe.
