Green Tea and Brain Cancer

Green tea and brain cancer study found that regular consumption suppresses tumor.

A 2010 study conducted by Korea Institute of Science and Technology found that caffeine blocks the growth of inositol trisphosphate receptor (IP3R).

This substance is closely linked to glioblastoma, which is the most common and aggressive type of primary brain tumor found in human. According to Xinhua, a sub-type of IP3R, or IP3R3, is very active among brain cancer patients.

Caffeine stymies the spread of such compounds, resulting in less tumor growth in the brain and blocks cancer cells from spreading to other parts of the body.

"This is the first type of discovery showing caffeine to have an inhibitive effect on the growth of glioblastoma, and thus, we expect it to have monumental impact on related studies," said Lee Chang-joon, who led the study.

The researchers said that the amounts of caffeine used in the animal tests were somewhere in the range of two to five cups of coffee or green tea per day.

The discovery was published in the latest issue of U.S.-based Cancer Research Journal.
