Monday Aug 8, 2011 (foodconsumer.org) -- A meta-analysis in the May 2011 issue of Medical Oncology suggests that eating too much, meat, particularly red meat and processed meat may increase risk of bladder cancer.

The study showed men and women who ate highest amounts of red meat and processed meat were 17 and 10 percent more likely to be diagnosed with bladder cancer, compared with those who ate lowest amounts.

Early studies are inconsistent when it comes to how meat consumption affects the risk of bladder cancer. The current study was intended to examine the association by analyzing pooled data from multiple studies.

C. Wang and H. Jiang of Zhejiang University in China found the correlation after analyzing data from 21 studies - 10 cohort studies and 11 case-control studies published prior to Oct 2010.

However, the researchers did not find an overall association between meat consumption and risk of bladder cancer.

In the analysing of data from subcategories, the researchers found studies conducted in the U.S. and Canada linked high meat consumption with increased risk of bladder cancer. 

Also, studies based on data from self-administered food frequency questionnaires showed a significant association between high meat intake and elevated bladder cancer.
