Our analysis of worldwide research on bladder cancer
As part of the Continuous Update Project (CUP) – our ongoing programme to analyse global research on how diet, weight, physical activity and nutrition affect cancer risk and survival – we have analysed worldwide research to produce our report on bladder cancer.
Published in December 2015, the report is the most rigorous, systematic, global analysis of the scientific research currently available on diet, weight, physical activity and bladder cancer, and which of these factors increase or decrease the risk of developing the disease.
The total number of adults in the 45 studies from around the world reviewed for the report was around 7 million; and the total number of bladder cancer cases in the studies analysed for the report was almost 37,000.
There is strong evidence that drinking water containing arsenic increases the risk of bladder cancer. The evidence on this link is now stronger than in the worldwide evidence we reviewed for our 2007 Second Expert Report.
