Green tea consumption not shown to reduce risk of breast cancer.

A study conducted by the Japanese Public Health Center looked at the risk of breast cancer in ~54,000 women followed for 13.6 yrs.  They found no protective effects in women who consumed green tea.  Other researchers point out that the results hightlight the difficulties of performing population studies.  It is not possible to consider all the behaviors and risk factors in large populations.
