A new study has found that consumption of moderate amounts of green or white tea might provide a protection against colon tumors about as well as a prescription drug, sulindac, that has been shown to be effective for that purpose. The research was just published in the journal Carcinogenesis by scientists from the Linus Pauling Institute at Oregon State University, in studies funded by the National Cancer Institute. It may suggest some optional approaches to cancer prevention or therapy, especially for people who have trouble with the side effects that can be associated with regular use of non-steroidal anti-inflammatory drugs, or NSAIDs, such as sulindac or aspirin.
