“…We identified 28 studies on the risk of bladder cancer and tea consumption between 1980 and March 2012 [11,12,13,14,21,22,23,24,25,26,27,28,29,30,31,32,33,34,35,36,37,38,39,40,41,42,43,44]. After a closer examination, 10 studies were excluded due to lack of information [35,36,37,38,39,40,41,42,43,44].…”

“…In addition, another study was abandoned for duplicated data [34]. Finally, a total of 17 studies including 8,225 cases were involved in our analysis [11,12,13,14,21,22,23,24,25,26,27,28,29,30,31,32,33]. Among the chosen studies, 4 were cohort studies [21,22,23,26] and 13 were case-control ones [11,12,13,14,24,25,27,28,29,30,31,32,33].…”

A Meta-Analysis of Tea Consumption and the Risk of Bladder Cancer

Objective: Previous studies on the association between tea consumption and bladder cancer risk have only illustrated contradictory results. The role of tea in bladder carcinogenesis still remains conflicting. In order to illustrate the potential relationship between tea consumption and bladder cancer, a meta-analysis of case-control and cohort studies was conducted. Methods: Eligible studies were retrieved via both computerized searches and review of references. Stratified analyses on types of tea, gender, study design, ethnicity and smoking status were performed. Fixed- or random-effect models were used to summarize the estimates of OR with 95% CIs. Results: Seventeen studies were eligible for our analysis. No statistical significance was detected between tea consumption and bladder cancer risk when comparing the highest with the lowest intake of tea (OR = 0.825, 95% CI 0.652–1.043). In the subgroup of green tea, we observed it illustrated a protective effect on bladder cancer (OR = 0.814, 95% CI 0.678–0.976). Conclusion: Our analysis indicated that green tea may have a protective effect on bladder cancer in Asian people. Further studies need to be conducted to better clarify the biological mechanisms.

“…Leong et al (2008) used the C3(1)/SV40 mouse model to evaluate the chemopreventive effects of green tea on human breast cancer, which showed that the administration of 0.5% polyphenol in drinking water significantly suppressed the development of tumor growth by 40% compared to tap water-fed animals. The association between green tea intake and breast cancer risk has been investigated in five prospective cohort studies conducted in Japan (Nagano et al, 2001;Suzuki et al, 2004;Iwasaki et al, 2010), Singapore (Yuan et al, 2005;Inoue et al, 2008), and Shanghai, China (Dai et al, 2010). These prospective cohort studies with a total of 2067 breast cancer cases, show that there is no association between the breast cancer risk and green tea drinking.…”

Originating in China, tea and tea planting have spread throughout the world since the middle of the Tang dynasty. Now people from 160 countries in the world are accustomed to tea drinking. A brief history of tea's medicinal role in China and its spread to the world are introduced. The effectiveness of tea active components and tea drinking on major human diseases, including cancer, metabolic syndrome, cardiovascular disease, and neurodegenerative diseases, is discussed. Also presented are some related issues, such as the bioavailability of tea active components, the new formulations of tea polyphenols, and the safety for consumers of dietary supplements containing tea polyphenols.
