Introduction: Prostate cancer is the most p-revalent cancer among males in econo-mically developed countries. Among the several risk factors suggested for prostate cancer, only age, ethnicity, and family hist-ory of prostate cancer are well- Prior stu-dies have shown that dietary intake can change cancer risk. Most data in this area was drawn from Western studies and dev-eloping countries have limited data in this regard. This study examined the association between black tea and coffee intake and the risk of prostate cancer in Iran.
 Materials & Methods: Cases were patients who were admitted to ‘Labbafi-Nejad Hos-pital’. Controls were patients admitted to the emergency service of the same hospital. The control and treatment group members were matched in terms of age (10years). A total of fifty patients with prostate cancer and a hundred controls underwent face-to-face interviews. We assessed participants’ dietary intakes during the past year by using a valid and reliable semi-quantitative food frequency questionnaire (FFQ). SPSS version 16 was used to analyze the data.
 Findings: a significant positive relationship was observed between consumption of bla-ck tea and prostate cancer risk (above medi-an vs. below median: OR = 2.9, 95%CI 1.0-3.0). We could not find a significant relat-ionship between coffee intake and prostate cancer risk (p=0.07)
 Discussion & Conclusion: The results of the present study suggest that high consu-mption of black tea might be positively related with an increased risk of prostate cancer.
Keywords: Prostrate cancer, black tea, coffee, case control study
