Tea consumption and prostate cancer

Abstract

Objectives

Tea is supposed to have chemo-preventive effect against various cancers. However, the protective role of tea in prostate cancer is still controversial. The aim of this study is to elucidate (explain) the association between tea consumption and prostate cancer risk by meta-analysis.

Methods

A total of 21 published articles were retrieved via both computerized searches and review of references…

Results

No statistical significance was detected between tea consumption and prostate cancer risk in meta-analysis of all included studies...Only the case–control study subgroup demonstrated a borderline protective effect for tea consumption against prostate cancer...

Conclusion

Our analyses did not support the conclusion that tea consumption could reduce prostate cancer risk. Further epidemiology studies are needed.
